Week 32 - Parallel MD

Reminder 1: There should always be 1 cycle reserved for parallel studies in the PSB => Check during the week the LHC beam with 50/75 ns bunch spacing in the PSB to be ready for the Injector Long MD of week 33.

Reminder 2: During the week (when possible) the PS will continue to work on the Matrix measurements with the 5-CM PFWs.

 

Monday 04/08 and Tuesday 05/08 (08:00 - 18:00) - Study of the TMCI at SPS injection + transverse impedance localization

Beam conditions: SPS user = MD1 (supercycle = SFT_LONG-3CNGS-LHCFAST-MD37_V1), PS user = MD4 and PSB user = MD3

#bunches = 1

Nb = San from ~ 1.0 x 1010 p/b to ~ 1.0 x 1011 p/b => Ask Klaus (Jocelyn) to adjust it in the PSB + Heiko to check that everything is OK in the PS

Transverse emittances: ex,y* are what the PSB can deliver (should be constant over the intensity range, because the intensity is changed with longitudinal shaving, i.e. by changing one vector of the C02 GFA)

Longitudinal emittance: eL* ~ 0.15 eVs

Contact person: B. Salvant and R. Calaga

 

Wednesday 06/08 (08:00 - 18:00) - Measurement of the SPS longitudinal impedance

Beam conditions: SPS user = MD1 (supercycle = SFT_LONG-3CNGS-LHCFAST-MD37_V1), PS user = MD4 and PSB user = MD3

#bunches = 1

Nb = San from ~ 1.0 x 1010 p/b to ~ 1.0 x 1011 p/b => Ask Klaus (Jocelyn) to adjust it in the PSB + Heiko to check that everything is OK in the PS

Transverse emittances: ex,y* are what the PSB can deliver (should be constant over the intensity range, because the intensity is changed with longitudinal shaving, i.e. by changing one vector of the C02 GFA)

Thursday 07/08 (08:00 - 18:00)

supercycle = SFT_LONG-3CNGS-LHCFAST-MD37_V1

- Preparation to the LHC injection test (09-10/08/2008) (following request from J. Wenninger 24/07/2008)

Beam required: LHCPROBE and/or LHCPILOT on the LHCFAST1.

Contact person: J. Wenninger

- Setting-up of the e-cloud measurements in the SPS to be ready for the Long MD of week 33

Beam conditions: SPS user = MD1, PS user = LHC25 and PSB user = LHC25A & B

Contact person: W. Hofle

MD plan: if possible, Wolfgang will use the MD1 segment with the nominal LHC beam, and Jorg will use the LHCFAST segment with PILOT and/or PROBE. In case of conflict, priority will be given to the preparation tests for the LHC injection test (J. Wenninger)

 

Friday 08/08 (08:00 - 18:00) - Check the LHC beams with 50 and 75 ns bunch spacings in the PS (to be ready for the Injector Long MD of next week 33)

Contact person: S. Hancock

Following request from J. Wenninger (24/07/2008)

- Preparation to the LHC injection test (09-10/08/2008)

Beam required: LHCPROBE and/or LHCPILOT on the LHCFAST1. There should be no conflict with Steve completing the setting up of the 50/75ns beams in the PS.

Contact person: J. Wenninger
