Get access to the ISOLDE facility

All ISOLDE Users and Associates needing access to the hall must fulfill the following criteria (CERN employees click here):

a) be in possession of a valid CERN ID card
b) have passed 3 online courses: "CERN Safety Introduction", CERN RP course for Supervised Radiation Areas " Radiation Protection - Supervised Area" and the Electrical Safety - Awareness Course  
c) have a CERN filmbadge (dosimeter). You will need a "certificate attesting the suitability to work in CERN's radiation areas" signed by your institute (see below).
d) have followed the 2 hour practical ISOLDE RP course and the new 2 hour practical electrical awareness course which take place once a week on Tuesdays 13:00-17:00 (see below for how to register for these courses)
e) have access to the hall granted via ADAMS

Access to the ISOLDE hall is now from the Jura side of the building only and via your dosimeter, not via your a CERN access card.

From 11th October 2016 onwards, access to the chemical Lab (508/R-002) and the measurements area (508/R-008) will also require the online course "Chemical Safety Awareness" found via .


More details about how to fulfill the above mentioned criteria:

Point a) should normally be fulfilled for any correctly registered ISOLDE User (see registration).

Point b) the online  "CERN Safety Introduction" course, Electrical Safety - Awareness Course  and the online RP course for Supervised Areas must be followed before you can get a dosimeter and access to ISOLDE.

If you have a CERN account (NICE) you can access the on-line courses mentioned in points b) and c) above from your computer, from both inside and outside of the CERN network. If you do not have a CERN account, you can complete the training using computers at your disposition in building 55 (first floor – Registration Service). Your CERN card will be needed in order to prove your identity.

Point c) a permanent dosimeter can be collected from the Individual Dosimetry Service in building 55, which is open from Monday to Friday from 08h30 to 12h00. To apply for a permanent dosimeter you will need a "certificate attesting the suitability to work in CERN's radiation areas"  (see bottom of page) signed by your institute. At the end of your visit to CERN, if you do not need your permanent dosimeter during the next 2 months, you must return it to the dosimetry service before you leave. If your registration/courses etc. are up to date you can pick it up again from the dosimetry service the next time you come to CERN.

Point d) follow the 2 hour practical RP safety course and the new 2 hour Electrical Awareness Module (available from April 2015), that take place together, for which you must register in advance. If you have already followed the RP safety course, register only for the electrical course. If you are already a CERN user and have a valid CERN computing account, please register online at least two weeks in advance via CERN Training Catalogue for the electrical and RP course separately. If you are not yet registered as a user, please pre-register for the courses first via email by sending the form found at the bottom of this page directly to the training centre specifying for which course you wish to register. The moment you register as a CERN user and obtain your CERN computer username and password, you are obliged to register for the above courses via the EDH system. Only after you've made the EDH final registration and you've followed the RP safety course, will your dosimeter be activated and you will have access to ISOLDE. The courses take place once a week (Tuesday from 13:00 to 17:00) at the CERN Prevessin site (using the regular CERN shuttle service). Dates of the course can ve found via the CERN Training Catalogue.

 If you do not have a permanent dosimeter and wish to work in the ISOLDE hall over a weekend, you will need to arrive at CERN on Tuesday morning otherwise you will only be able to work in the DAQ rooms in building 508 which are not in the controlled area..

Point e) can easily be arranged by an application through the CERN ADAMS system at and by requesting the "ISOHALL:ISOLDE(HALL)" access. Please note that "ISOLDE-PRIMAIRE (ISOPRIM)" and "ISOLDE GPS, HRS, HT (ISOGHH)" is not normally needed for ISOLDE Users. The access request can only be made if you are already registered as a CERN User and already have a CERN dosimeter.

If, after completing all of the required criteria listed above, you have problems with access to the ISOLDE hall you should check with the ISOLDE User Support Office, ISOLDE Physics Coordinator, or the 'Centrale de Surveillance d'access', tel: 78877 or

PLEASE NOTE: When you register as a CERN User, the computer system via which the access demand for the ISOLDE Hall is made will not be updated until that night. Hence, the access request cannot be made until the day after you have registered. This should be taken into account when arranging your visit to CERN.
