J.-P. Riunaud PS/AE PSMB 16/09/2002 Report from 59 th SPSC meeting - Closed Session (1/3) 1. Approval of the minutes of the 58th meeting 2. Matters arising 3. Report on the 159th meeting of the Research Board - Exchange of letters between L. Nemenov (DIRAC) and DG for an extension of DIRAC in Another letter (02/09/2002),sent to Research Board distributed to SPSC members 4. Status Report on the SPS - Status of CNGS work by P. Grafstroem : should be ready by mid What would be the consequences of a lower energy ? Answer at next meeting - Good efficiency and intensity in SPS this year. - Congratulations from SPSC. 5. Status Report on the PS - East Area back to 24 GeV/c, but frequent power supply trips. - AD operation on piquet regime from 09/09. - Intensities as required by users. - Congratulations from SPSC. 6. Status Report on the PS and SPS experiments - DIRAC lost 12 % of their data taking due to the transformer problem. - Long and successful proton run of NA49. - COMPASS had a difficult start. Now data taking is very efficient. - NA60 : high energy ion run cancelled because detector not ready. - NA48 has a 1 week extension (granted by DG) to compensate for the losses at the start.

J.-P. Riunaud PS/AE PSMB 16/09/2002 Report from 59 th SPSC meeting - Closed Session (2/3) 7. ICARUS Proposal SPSC /P323: V. Kekelidze - Will start data taking in 2003, with the T600 module tested in Pavia. - T3000 should be operational in Will use the CNGS beam. - Vast programme on p+ decay, atmospheric and solar neutrinos, … - SPSC recommends ICARUS for approval in consultation with the Gran Sasso Scientific Committee. - SPSC asks for detailed schedule and expects more information on financial and manpower resources. - Congratulations from SPSC. 8. Status Report on OPERA: S. Dalla Torre, R. Forty - Slight changes in detector lay-out (Changeable Sheet Detector will speed up scanning). - Withdrawal of CERN required some reallocation of responsibilities. - Production of emulsion and their life time dictate a stringent adherence to schedule. - SPSC expressed its worries about the tight schedule for the Brick Assembly Machine - SPSC supports the quest for higer beam intensity. - Congratulations from SPSC. 9. Status Report of NA59: D.Websdale - Written report requested. - Will be discussed at next meeting. 10. Status of NA60 (SPSC /M-690): I. Brock - Explanations on the problems encountered in the production of the pixel detector. - SPSC regrets the cancellation of the high energy ion run due to delay in the pixel detectors. - SPSC hopes that the detector will be complete for the run in 2003.

J.-P. Riunaud PS/AE PSMB 16/09/2002 Report from 59 th SPSC meeting - Closed Session (3/3) 11. SPS and PS schedules - Report on the schedule modifications this year : Cancellation of high energy ion run and 10 more days to low energy run. 1 more p+ week allocated to NA48. - Draft 2003 schedule presented : PS start 05/05 and 171 days of physics. SPS starts 19/05 with 105 days of physics & 7 days of "25 ns" operation (date to be discussed). Indium run from 17/09 to 26/ A.O.B. * Request for proton irradiation by C.A.Londos: J-P. Riunaud - There is no irradiation facility at CERN providing 10 MeV protons. - Study made by C. Hill and K. Schindl to use beam from Linac 2 : More than a week would be required at the and of the year, plus manpower. - Conclusions : Request should be adressed to another accelerator. * Letter of Intent (SPSC /I-225) from M. Holzscheiter et al.: Relative Biological Effectiveness and Peripheral Damage of Antiproton Annihilation. - Request to use the AD DEM line to sudy biological effects of p- anihilation. - A few hours / year before end 2004; 300 MeV/c extraction. - SPSC asks for a cost estimate of DEM installation (to be presented at november meeting). - A full proposal may then be requested to Holzscheiter et al.
