1. Minutes of last meeting (YB)
The minutes from the last meeting were approved.

2. HIE-ISOLDE (ML)
Mats reported (see file below) on the status of the HIE-ISOLDE proposal. It has been reconfigured into to different phases with HIE-ISOLDE 1 addressing the energy upgrade, the beam quality improvements (on-going) and a design study for the intensity upgrade. The second phase, HIE-ISOLDE 2, would include the intensity upgrade itself, the super HRS and any possible remaining part of the energy upgrade.
Peter Butler brifely discussed the status of the UK HIE-ISOLDE linac proposal.

3. SPL options for HIE-ISOLDE (RG)
Roland reviewed (see file below) the different options for protons for the present ISOLDE facility from SPL. Light SPL will be able to deliver up to 40 kW to the present ISOLDE area (later revised to 30 kW) at 1.4 GeV. Different improvements would enable up to 150 kW-1.6 MW for ISOLDE which is not realistic without a new EURISOL like target station. Roland offered his support for presenters at the New physics opportunities workshop regarding the SPL options.

4.Intensity upgrade (RC)
Richard described the existing ISOLDE target area and the on-going effort to create a comprehensive set of drawings for the area. He also discussed possible paths towards a higher intensity target area.

5.HIE-ISOLDE, impact on targets (TS)
Thierry presented (see file below) the consequences an intensity upgrade would have on the targets of ISOLDE. He presented the on-going work to improve the diffusion and effusion times and the life time of targets. he stressed the importance of developing new target materials but also thermal management and reliability.
A discussion followed on the comparison to SPIRAL-II. It was agreed that if only driver beam power is considered SPIRAL-II will have an advantage for elements produced by fission and which are long lived.
The issue of what the objectives should be for the optimisation of targets at HIE-ISOLDE. It is clear that targets can be designed to e.g. produce high intensity of long-lived elements, for fast extraction and/or for long target life time. We should choice an optimisation path which gives HIE-ISOLDE a distinct advantage compared to other facilities operating at the same time.

6. Priorities for Target R&D at ISOLDE (TS)
Thierry summarised (see file below) the priorities for target R&D in 2009. No new activities will start in 2009 due to a lack of manpower in the section. However, there are a number of on-going activities such as the measurements of the beam profile on n-converter and the n spectrum/flux, 6He production from (n, alpha) on BeO and test of GdB6 low work function cavity for rare earths. If the high density UC arrives from Russia in time a test of these new type of UC is also scheduled.
