At the occasion of this last meeting, J.P. Delahaye warmly thanked the PSMB for the fruitful collaboration during the period of 3 years he has been Division Leader. He particularly appreciated the team spirit of the PSMB which made it possible to always come to a consensus when taking decisions.

1. Recommendations of the Working Group and PPC of the study of the Booster cycling at 0.6 sec (M. Benedikt and R. Cappi).

J.P. Delahaye congratuled M. Benedikt for the excellent presentation at the PPC last week as well the whole team for all the work done, with very little means, in the framework of this study. The aim of the study is to explore the possibility to increase the number of PSB cycles available for the users by 67%. During this meeting M. Benedikt summarized the conclusions of the tests that were done during the last two years, listed the cost of several scenarios, the major impact on other areas, and recommended future activities to take place during the 2002 shutdown and in 2003. These were approved by the PSMB. It was also decided to document the results and to continue the study on the impact of all the users (and not only ISOLDE) in the framework of the "High Intensity Proton" study. The HIP Working Group (Members: M. Benedikt, K. Cornelis, R. Garoby (chairman), E. Metral, F. Ruggiero and M. Vretenar) is in charge of preparing recommendations to the management of the AB division for the evolution of the proton accelerators at CERN.

2. Follow-up of previous meeting and matters arising

3. Shutdown work

4. PS Consolidation Project (J. Gruber)

A Draft note was sent to the PSMB for approval. J. Gruber summarizes the status of 2002. The total commitment for 2002 was 770 KCHF (740 foreseen). Funds for the PS Consolidation are ensured by the P082 Project, but were usually topped up by divisional subventions. However, due to the general saving measures, the latter were substantially reduced since 2000. Therefore consolidation has now to concentrate on indispensable renovation work to ensure the functioning of the LHC and its detectors. J. Gruber presents his program including resources (budget, CERN manpower, Industrial Support) mentioning that actually some 4 to 5 m-years of Industrial Support is already working on the consolidation in progress, financed by the normal exploitation budget. This part of the actual Industrial Support budget (380 KCHF) should remain to be allocated during the next years of the consolidation budget. K. Schindl suggested to mention the ISOLDE program consolidation project and to emphasize in the conclusions the fact that this project just deals with consolidating items needed for the LHC.

5. Operation statistics and the 2nd job of the operators during the shutdown (S. Baird)

S. Baird presented a selection of items which will be published in the Annual Report such as the PS Complex accelerator machine statistics, beam statistics, the distribution to the users of particle beams accelerated in the PS in 2002, such as proton beams for SPS, TOF facility, AD, LHC tests, ISOLDE. An analysis of fault rates will also be given.

Following the PSMB of 22.11.2002, the list of 2nd job of operators during the forthcoming shutdown has been completed by additional requests. The number of total requests now exceeds the available manpower. Several "high priority" requests are not satisfied (mainly due to the top priority of the LHC magnet measurements) so the Group Leaders concerned are asked to make a critical review of the list and propose operators able to execute these requests. These proposals will be collected and discussed in a special meeting (action: S Baird). Once the final list is ready, a memo will inform operators and supervisors of their duties. J.P. Delahaye underlines the importance of the operators being fully integrated in the technical groups during the (5 months!) shutdown in order to get fully experienced. The 2nd job's supervisor normally should be member of the technical group, and will have to participate in the MAPS exercise of his supervisee.
