Week 36 - Parallel MD
Reminder 1: There should always be 1 cycle reserved for parallel studies in the PSB.
Reminder 2: Most of the time during the SPS ion commissioning (i.e. between week 33 and 38), the LHCION1 cycle will be added (during the day) to the SFTLONG + 4 CNGS1 cycles in the SPS. The corresponding ion cycle in the PS is LHCION. However, the cycle MDION should also be available in the PS to work on the nominal ion beam. J. Burnet agreed to increase the PS load from 5 to 5.4 MW to be able to have both LHCION and MDION in the PS (R. Steerenberg, 17/08/09).
Reminder 3: During the week (if / when possible) the PSB and the PS will continue to work on the production of LHC75 and LHC50 in 1 batch.
Monday 31/08 (08:00 - 18:00) to Wednesday 02/09 (08:00 - 18:00) -
SPS ion commissioning (setting-up in // of the early ion beam)Beam conditions
: SPS cycle = SFTLONG1 + 4 CNGS1 + LHCION1, PS user = LHCION (MDION is reserved for the nominal beam) and LEIR user = EARLYSPS user Timing = LHCION1 (LHCION2 is reserved for the dedicated MD)
Contact Person: D. Manglunki
Thursday 03/09 (08:00 - 18:00) - TMCI studies for single-bunch feedback => Cancelled (due PS problem)
Beam conditions
: SPS user = LHCFAST2 (SPS cycle = SFTLONG1 + 3* CNGS1 + LHCFAST2), PS user = MD4 and PSB user = MD3#bunches = 1
Nb = Scan from ~5E9 p/b to ~ 1E11 p/b => Ask Klaus to adjust it in the PSB + Heiko to check that everything is OK in the PS
Transverse emittances: e* ~ 1 microm (we take what the PSB can deliver => Will vary with the vertical shaving)
Longitudinal emittance: eL* ~ 0.15 eVs
