Invited: M. Calviani (P.T.)

The meeting starts at 10:30 h

1. Welcome, approval of minutes, matters arising – J. Pakarinen

The ISCC Chairperson, J. Pakarinen, opens the 105^th meeting of the committee and welcomes the participants. The committee welcomes the new Belgian representative, A. Koszorus. The Chairperson informs the committee that E. Nacher and V. Ingeberg replace the Spanish representative, I. Martel, and the Norwegian representative, S. Siem, respectively at this meeting.

The agenda of the meeting and the minutes of the previous meeting are approved.

2. Reorganisation of SY-STI Group – M. Calviani

The committee welcomes M. Calviani, the new SY-STI Group Leader, to the meeting who then presents the responsibilities and priorities of the group. The Deputy Group Leader is now A.P. Bernardes and from April 2026, the SY-STI group will be made up of the following sections:

• Beam-Matter interaction Physics (BMP) – Section Leader: A. Lechner
• Beam intercepting Devices Engineering (BDE) – Section Leader: A. Perillo Marcone
• Target Systems & Projects portfolio (TSP) – Section Leader: J. Vollaire
• Radioactive Beams Production (RBP) – Section Leader: C. Duchemin
• Laser systems and pulsed Particle Sources (LPS) – Section Leader: S. Rothe

It is explained that the reorganization of the group will help achieve the goals of the CERN 5 year plan. J. Vollaire will continue as the ISOLDE Technical Coordinator and points of contact for ISOLDE will remain the same i.e. S. Stegemann will still be responsible for targets and S. Rothe for lasers. O. Fjeld will also move with J. Vollaire to the new TSP section; M. Calviani assures the committee that the technician will continue to work exclusively for ISOLDE as his position is fully funded by the collaboration.

3. Follow up on improvement plan– E. Siesling

The ISOLDE Long Shutdown 3 (LS3) planning is presented. While the start of LS3 for the CERN injector chain will be at the end of August 2026, due to the beam dump replacement project (IBDRS) the long shutdown at ISOLDE already started when the delivery of protons stopped at the end of 2025. The current plan is for protons to be again made available to ISOLDE on 8^th May 2028.

The management structure of the ISOLDE Improvement Programme has been put in place and is presented to the committee. E. Siesling reminds the committee that the successful 2025 MTP request that was a COFUND request with the ISOLDE Collaboration and made to compliment the consolidation budget, has provided a total of 6.75 MCHF towards the facility’s improvement plan of which 3.74 MCHF will be provided by the ISOLDE Collaboration. The programme Charter and budget structure is being drafted and will be circulated when completed.

E. Siesling presents the status of improvement plan activities as well as those of the major experiments. The committee is told that, as expected, the large number of co-activities in the ISOLDE hall with contractors working in parallel with CERN staff and Users makes the coordination and keeping a general overview a challenge. Despite this, all planned activities are on schedule. The weekly ISOLDE Technical Meeting covers the ongoing activities and maps those coming up to avoid clashes and maintain the best possible access to the hall and the areas around the facility. Handling and blockage of the crane needs particularly careful planning; good collaboration has been established with the transport service with a direct contact person, Y. Seraphin, attending the ISOLDE Technical meetings. A weekly schedule with overview of the various activities has been initiated by H. Heylen and is available on the ISOLDE website https://isolde.web.cern.ch/isolde-hall-activities-ls3 . The committee is told that, depending on the schedule, access to the hall will be restricted from time to time which could affect visits. E. Siesling explains, apart from short term shipment and handling, the SAS must be kept free, especially during transport and handling of CM1 and PUMA, to ensure the smooth progressions of projects.

The committee is told that, as part of the improvement programme, the BTY line 2.0 GeV upgrade involves the consolidation of power supplies which, due to space requirements, means the future of the MISTRAL power supply needs to be decided.

As part of the LS3 REX low energy consolidation work it was planned to purchase a spare REXTRAP solenoid. E. Siesling explains that the cost of such a spare has almost doubled hence discussions are ongoing to decide whether or not it might be more prudent not to purchase a spare solenoid and use the then available 470 kCHF from the Consolidation budget to forward other approved requests. At present, funding for the new 9 Gap RF Amplifier is included in the 2026 MTP request and it may be better to prioritise this request rather than including a request for the increased cost of a spare solenoid. The committee states that, if the local groups decide to take this route, it would support this decision. The replacement of the REXTRAP solenoid would be a major intervention and could not take place during a run; if a spare solenoid is not available and the present solenoid fails then an urgent request could be made for the approval to launch the procurement of a replacement and in the meantime attempts could be made to repair the failing solenoid and the REXTRAP could continue to run in degraded mode from HRS.

The planning established by SY-RF to achieve the refurbishment of cryomodule 1 (CM1) taking into account the availability of the required experts is presented. Activities are scheduled until April 2027 with CM1 due back at ISOLDE in October 2027. The production of the spare cryomodule (CM5), which will be funding by 1.7 MCHF of the collaboration’s contribution to the ISOLDE improvement programme, is due to get underway with the start of procurement in 2027; CM5 should be ready for YETS 2030/2031. The committee is told that support for the procurement in 2027 is to be re-assessed and is still to be confirmed in the context of LS3. There is always the possibility that the high number of CERN priorities during LS3 might jeopardise the ISOLDE CM5 production plan so the committee agrees that it is very important that the strategy and commitment towards the production of CM5 needs to be reaffirmed by the departments, groups and services involved and to be solid.

E. Siesling tells the committee that the motivation of all the teams, contractors and groups involved in activities at ISOLDE is very high and thanks everyone involved in work carried out so far.

4. Follow up on experimental activities– L. Fraile

L. Fraile expands on some of the information already presented by E. Siesling on the status of experimental activities in the ISOLDE hall.

• The MIRACLS setup has been removed and the space vacated has already been distributed to other experiments.
• The PUMA collaboration is taking care of the RC7 line extension required for their experiment.
• The installation of MULTIPAC on the ground floor of building 508 is ongoing.
• Space for the ISRS test bench in building 275 is still to be identified.
• VITO plans for modifications are being discussed.

L. Fraile stresses the need for communication from ISOLDE Users on their activities during LS3.

The committee is told that C. Porzio will assist the team, lead by K. Chrysalidis and A.P. Bernardes, working on the replacement of the RILIS laser barrack; she will coordinate the physics side of the project.

L. Fraile reminds the committee that offline “standalone” physics runs are possible at the facility in 2026 with the window of opportunity, when services are available, being from March to August. It will be possible to run experiments with long-lived sources and discussions are ongoing with potential source providers including ILL and MEDICIS.

5. Update from the Physics Coordinator – H. Heylen

A brief summary of the 2025 physics run at ISOLDE is presented. During 255 days of physics, 450 shifts were delivered to 51 INTC approved experiments, of which 12 were HIE-ISOLDE, and 4 letters of intent. The distribution of delivered shifts between different areas of physics is shown. H. Heylen then mentions a couple of the many physics highlights from 2025 as well as the experiments that required derogation to run at 2.5 uA.

The committee is told that two weeks before the end of the physics run, a leak was detected in the cooling water circuit of one of the magnets in the BTY line towards the HRS target station. With the help of experts at ISOLDE the facility was able to continue to run although it was limited to 30% of NORMHRS in supercycle.

The percentage of CERN protons delivered to ISOLDE during 2025 is presented with the average being 65% (this includes MEDICIS irradiations on top of protons on ISOLDE targets). L. Fraile informs the committee that CERN has approved the SHIP experiment that is due to go online at the end of run 4 and will take up to 70% of CERN protons. An ATS working group on the fixed target programme for the SHiP era has already been set up and will report to the Injectors and Experimental Facilities Committee (IEFC). The committee agrees that this should be closely followed to clarify the possible impact on the ISOLDE facility and how it could be accommodated.

H. Heylen summarises feedback received from the technical teams on the 2025 schedule. One point raised is that more feedback from the experimentalists after the run would be appreciated. To follow up on this, a questionnaire about many aspects of running an experiment at the ISOLDE is being prepared and will be sent out to, among others, experiment spokespersons, the ISCC and the ISOLDE physics group. One suggestion that has already arisen from feedback is the possibility of splitting the “start-up” meeting into two parts with a general meeting several weeks before the experiment run to cover, for example, safety, readiness expectations and missing information and then a short meeting with only the spokesperson and the technical teams at the start of the experiment.

Statistics on the shifts delivered by the ISOLDE facility during the CERN Run 3 from 2021 to 2025 are shown. There was a slight upward trend in the total number of shifts delivered each year over this period with a total of 1824 shifts delivered during Run 3 to 114 different experiments and 20 letters of intent. There were 1320 shifts on the books at the start of Run 3 and at the end of the running period the backlog is now 1220 shifts for 121 experiments/LOIs. There are 56 INTC approved experiments/LOIs that haven’t been given beam since approval. During the period from November 2021 to November 2025 the INTC approved 1623 shifts.

H. Heylen then makes the following announcements:

• With many major upgrades ongoing, coordination of activities in the ISOLDE hall is necessary so the User community is asked to inform the Physics Coordinator of their plans for work in the hall during LS3.
• When making changes to experimental setups the ISOLDE hall integration drawings must be updated accordingly.
• During LS3 the hands-on ISOLDE-RP training course will only take place once a month but the 1-day course “Radiation Protection – Controlled Area”, that can serve as an alternative to the tailored ISOLDE course, takes place every Wednesday. The hands-on “Electrical Safety – Working in EP experiments” course will continue to be given weekly.
• ISOLDE Users can sign up to the ISOLDE information mailing list via e-groups.cern.ch .
• Management of the use of space in building 275 is taking place.
• Visits of the ISOLDE facility remain extremely popular. However, due to ongoing upgrades and shutdown activities, up until at least the end of 2026, the reserved time slots for visits will be Wednesdays from 14:00 to 16:00 and Fridays from 10:00 to 12:00. Other slots will be considered if guides can be found and the work in the hall allows. Depending on ongoing activities, at sometimes visits might be restricted to the 508 meeting room or part of the ISOLDE hall.

The committee is informed that CERN has launched a new procedure for requesting invitation documents for visas and Convention d’accueil (CA) documents required by all non-EU citizens. For registered Users the new EDH document to request documents can be launched by the person themselves or the Teamleaders.  The request for documents for new Users can be made via the EDH PREG document after it is approved by the Users office. The EDH invitation document will always go to the Teamleader to sign; the Users Office have set up a help page regarding this matter https://usersoffice.web.cern.ch/help-page-invitation-letter-obtain-visa-or-convention-daccueil. Please note that:

• The Teamleaders name will appear on the invitation letter (no longer the ISOLDE Spokesperson). An invitation letter will be created even if only a CA document is required.
• The Teamleader (institute) is responsible for the person concerned while they are using any visa acquired using the invitation documents provided by CERN.
• The invitation documents are professional documents and only to be used for coming to work at CERN.
• The Teamleader (institute) is responsible for making sure the documents are only used for coming to work at CERN.
• If someone leaves the institute before the end of their User registration then the Teamleader must ask the Users office to close the person’s registration, and this will render any associated invitation documents invalid.

6. ISOLDE users and safety structure – L. Fraile

The committee is informed that, as of the end of 2025, the CERN human resources database showed 630 active ISOLDE users while 989 users appear in the Greybook https://greybook.cern.ch/ . In 2025, Users of more than 49 nationalities from more than 27 countries came to ISOLDE. There are over 200 teams at ISOLDE which is a relatively large fraction of EP teams. However, ISOLDE only has 0.5 FTE User support and no dedicated experiment support.

Each team has a Teamleader, officially appointed by the Home Institute, who has to pass the mandatory team leaders e-course https://usersoffice.web.cern.ch/cern-e-learning-course-team-leaders . The Home Institution is responsible for informing the Users Office of any change of appointment. The responsibilities of the Teamleader and safety correspondent can be found via:

https://usersoffice.web.cern.ch/sites/default/files/pdf/Team%20Leaders/Home_Inst_CERN_TL_SC_Responsibilities.pdf

Some of the obligations of a Teamleader are:

• in collaboration with the Safety Correspondent (where the team leader does not act as safety correspondent) to ensure that the team members are aware of the CERN Safety Rules and procedures and of the obligation to comply with them.
• to ensure that there is an acting safety correspondent at all times. The Safety Correspondent can be nominated using the form found via https://usersoffice.web.cern.ch/safety-correspondence .
• to ensure that their team members complete all CERN Safety courses, CERN Computing Rules
• to initiate the online pre-registration of new team members and verify data

L. Fraile explains that the Safety Correspondent is the contact person responsible for ensuring that the institution is fully aware of any specific working conditions, including any specific hazards that its collaborators may encounter at CERN, so that the institution can exercise its responsibility as the home institution in this respect. The Safety Correspondent must ensure that all safety relevant information he/she receives from CERN (for example, information regarding work in CERN radiation areas or areas where a magnetic field is present) is channelled to the appropriate person in the institution so that he/she can act upon it. Also, the Safety Correspondent must ensure the follow-up by his/her institution of any requests relating to Safety from CERN and must ensure that the necessary certificates for work in radiation areas are issued.

The committee is informed that the review of the status of the ISOLDE SIAG recommendations has been completed; the revision of EP safety organisation and mandates has been finalised with EXSO and DEXSOs already in place. However, mandates within the SY and BE departments are still to be signed. Discussions are on-going about how to clarify the management structure within each permanent setup at ISOLDE where the Safety Contact Person should be aligned with the existing CERN role of Safety Correspondent.

L. Fraile reminds the committee that, at the ISCC meeting in October 2025, the proposal to set up an ISOLDE collaboration safety group to help address safety related questions and liaise with CERN was approved. This will be a small group made up of the ISOLDE spokesperson, the chair of the ISCC, the physics coordinator and two other non-CERN members who would together cover the main areas of physics carried out at the ISOLDE facility. J. Cubiss and L. Pereira have accepted to be the two non-CERN members of the ISOLDE collaboration safety group; the committee approves their nomination. The mandate of the group needs to be clarified with EP Safety after which it will be presented to the ISCC.

7. INTC matters– M. Pfützner

It is explained that during LS2 experiments with shifts remaining were asked to present a status report and they all requested to keep their shifts. This meant that the backlog of shifts at the end of run 2 could not be reduced and was transferred to the start of run 3. To avoid a similar situation occurring during LS3, the CERN research board accepted a proposal to make approved shifts valid only for the current running period. Hence, all experiments will have their remaining shifts set to zero at the end of LS3 and new proposals will have to be submitted to the INTC. The new INTC Chairperson, S. Leoni, who’s mandate starts at the end of March 2026, will set the procedure for the closure of experiments and the collection of new ones.

A discussion takes place about how collaborations pre-screen their proposals before they are submitted. It is understood that collaborations work differently and that the current communication with the ISOLDE Physics Coordinator does give the required results. However, it is suggested that guidelines could be provided to assist the collaborations to set their priorities and that the SGUI (Standing group for the Upgrade of ISOLDE), which is defined in the ISOLDE MoU, be resurrected to collect information and discuss necessary actions for the upgrade of the facility. L. Fraile will put together a proposal for the setup of the SGUI for the next ISCC meeting.  

M. Pfützner reminds the committee that INTC approval is given on scientific merit only and stresses that it is the responsibility of the Technical Advisory Committee, that considers the proposals before they are presented to the INTC, to decide if they are actually technically possible and adhere to all safety constraints.

The committee is told that the CERN SPC (Scientific Policy Committee) has requested that a review of ISOLDE and n-ToF activities be presented at its meeting in March. The ISCC agrees that L. Faile should present the requested review.

8. Collaboration matters– L. Fraile

L. Fraile informs the committee that the topical issue (“focus point”) on ISOLDE, which will be published in The European Physical Journal Plus, is now open for submissions. The publication will cover the ISOLDE programme in connection with an INTC review; original papers will be accepted including reviews, research and technical articles as well as future plans and upgrades. Discussions are taking place with several experimental and technical groups about possible contributions. The final submission date is September 2026.

The committee is told that in 2025 there were 17 PhDs defended that were linked to research carried out at the ISOLDE facility and that the available number over the past 6 years is approximately 15 theses per year. On behalf of the ISOLDE Thesis Award Selection Committee, W. Nörtershäuser updates the ISCC on the protocol being put in place to award the ISOLDE PhD prize that will be granted by the ISOLDE collaboration to young scientists from the member states in recognition of outstanding research achievements connected to ISOLDE and associated with their PhD study in the field of nuclear physics. At least part of the data used for the PhD should come from research carried out at the ISOLDE facility. The timeline decided on by the selection committee is as follows:

• 1^st May: The call for nominations will be announced. Supervisors can nominate their students who have made their defence between 1^st August the previous year and 31^st July the current year. The supervisor will have to provide a nomination letter, the date of the defence, and the student’s CV and publication list as well as give access to the thesis.
• 31^st August: This will be the deadline for nominations.
• 1^st October: The decision will be announced.

The winner will be able to present their work at the ISOLDE Workshop at the end of the year. They will have the workshop fee waived as well as having the cost of their stay in the CERN hostel covered during the event. Whether or not it is possible to fund the winners travel to the workshop is under discussion; the payment of a monetary prize is not possible.

L. Fraile reminds the committee that the Collaboration is committed to providing 3.7 MCHF towards the ISOLDE Improvement programme over the period up to and including 2030; spending already began towards the end of 2025. Two dependent third party accounts to the collaboration account have been set up to manage the improvement programme expenditure.

The financial status of the collaboration is then presented as well as its expenditure during 2025. All members have paid their fees for 2025 except Spain that still has 26 kCHF outstanding. The account balance is healthy even considering the expenditure already committed over the next five years. Foreseen savings and expenses, other than the improvement programme, are then discussed. While the collaboration will no longer be asked to contribution towards the cost of the ISOLTRAP platform, a contribution towards the new CRIS/COLLAPS platform is still under discussion. While savings were made for technical support in 2025 by moving costs to EURO-LABS, in the near future the collaboration will have to consider increased costs for user support as well as financial assistance for short term user visits depending on the availability of other funding projects. It is expected that a request will be made to the ISCC for the continuation of funding of the ABT fellow working on beam optics during the period 2026 to 2028 as well as requests for items for R&D and offline projects postponed from the 2025 MTP funding request. The ISCC should also consider the possible funding of user driven requests that have been compiled as well as other future projects; the collaboration may be asked to provide funding for the new LN2 tank. The committee agrees to increase the amount available for the User Support post to compensate for changes in tax situations applied to the present contract.

L. Fraile informs the committee that, at present, CERN management does not require any changes to be made to the ISOLDE MoU. However, the ISOLTRAP MoU is under revision with management requesting improvements and changes such as having a link to the ISOLDE MoU and an appropriate responsibility structure; this may potentially impact the ISOLDE MoU. It is expected that the revision of the MoUs of other experiment setups will follow; the MINIBALL MoU is already on hold.

Experiment spokespersons are reminded of the obligations attached to receiving EURO-LABS support; any resulting publications must acknowledge EURO-LABS and be GOLD open access and a data management plan must ensure open data. The EURO-LABS project runs from September 2022 to August 2026. However, due to the start of LS3 at ISOLDE at the end of 2025 all the Transnational Access funds (330 kCHF) have already been distributed to users of the facility; an extra 20kCHF transferred to ISOLDE in October 2025 was used to improve the support to users up to until the end of 2025. Hence, the total support provided to Users by the project was 350 kCHF. EURO-LABS Access funds were used to support a fellowship position but, due to the person being given a CERN LD contract, 83 KCHF of this funding remained and, as mentioned above, was used to cover the cost of technical support in 2025. An extra distribution within the EURO-LABS project, yet to be confirmed, would see ISOLDE receiving an extra 100 kCHF. Use of extra funds is under discussion with CERN finances with the aim to cover costs currently charged to the collaboration.

L. Fraile informs the committee that the INFRA-SERV-03 proposal was approved by the EU with the project focussing on hadron physics. P. Greenlees and S. Leoni were invited to be part of the steering committee to provide links to nuclear physics; M. Lewitowicz presented a single nuclear physics LoI for 2.5 M€ highlighting “broad” areas. It is not yet clear what funds will be made available to ISOLDE and what it could be used for. However, any funds received would be much reduced compared to EURO-LABS so the collaboration may have to provide financial support to users during the next running period.  

The committee is told that the 2025 ISOLDE Workshop was very successful with 20 invited talks, 33 contributed oral presentations and 47 posters making a total of 100 contribution. There was a total of 289 participants with 167 attending in person and 122 online. Preparation for this year’s event is already underway.

Note: proposed updates to annexes of the ISOLDE MoU, previously discussed by the ISCC, were confirmed via email on 6^th March 2026.

9. News from the local group – L. Fraile

The committee is reminded of the new CERN management structure put in place by the new Director-General, Mark Thomson, for the period 2026 to 2030. The changes most relevant to ISOLDE are that M. Calviani has taken over from S. Gilardoni as the SY-STI group leader with A.P. Bernardes as deputy group leader; within this group Charlotte Duchemin will be responsible for radioactive beam production. In the BE (Beams) department, B. Mikulec is the group leader of BE-OP (Operations) with M. Solfaroli Camillocci as the deputy group leader; within this group J.A. Rodríguez (BE-OP-IS) is responsible for ISOLDE.

The committee is told that, as part of the CERN strategy for diversity programme, the Director-General, plans to develop “a long-term vision and roadmap to exploit the CERN injector complex, in order to deliver an exciting, diverse programme of experiments for Physics Beyond Colliders” ; a new project office has been set up to work on a 20 year roadmap for non-collider physics at CERN. The committee agrees that it is very important for ISOLDE to be part of this discussion and it should be seen as an opportunity for the facility.

10. Next ISCC meetings in 2026/2027, ISOLDE Workshop 2026

The dates of the ISCC meetings in 2026 are decided as follows:

• 9^th June (virtual meeting)
• 10^th November (virtual meeting)

Dates of the ISCC meetings in 2027 will be fixed at the next meeting at which point the INTC dates for next year should be known.

In 2026 the ISOLDE Workshop and Users meeting will be held at CERN from 25^th to 27^th November.

11. Open discussion, A.O.B.

• A discussion takes place about how RP colleagues only being available on weekdays can affect an experiment run. Feedback from experiments is both positive and negative. It is suggested that the proposed ISOLDE Collaboration Safety committee discuss the possibility of nominating someone involved in an experiment to be allowed to carry out required interventions without an RP representative being present.

Meeting ends at 14:43.

N.B. The above presentations can be found via https://indico.cern.ch/event/1645256/  .
