1. Post-mortem of shutdown work (R. Brown)

Due to the cooling water problems (see PSMB meeting of last week), it was not possible to complete all the programmed magnet tests in the PS Ring. R. Brown presented slides listing day-by-day all the problems encountered during the 2 weeks' test period and concluded with ideas for the future. He pointed out the lack of time in case of a serious problem. The PSMB agreed that the test period is too short and should be extended by one or two weeks, and based on the experience of the last years, a schedule should be made (including a safety margin) for the whole PS Complex and regular follow-up meetings (weekly, or daily; depending on the evolution of the tests) should be organized. A coordinator will have to be nominated (Action S. Baird). Now that the shutdown period is longer than before, the work will have to be organized differently and J.P. Delahaye encourages all the PS Group Leaders to think about this subject.

2. Follow-up of previous meeting and matters arising

3. Follow-up of the Schedule Meeting and PS Complex Operation

4. Report from the LHC Technical Board

K. Schindl presented a summary of the LHC TB meeting of 9th April 2002, including the reports of the various sub-committees. Of particular interest for PS division was a meeting of the LCC (LHC Commissioning Committee) on the LHC Ion Programme. It became clear that the performance with lead ions will be rather marginal due to various limiting effects, but that the users insist on the importance of a high luminosity. As for the other (lighter) ions, there is no clear answer yet on the guidelines to follow. The overall ion project is not yet mature and therefore needs a Project Leader and a comprehensive Design Report. A review of the LHC Ion Project (organized by C. Wyss) with external reviewers will be held later this year.
