Week 35 - 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 24/08 (08:00 - 18:00) to Tuesday 25/08 (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 = MDPRO* and LEIR user = EARLY

SPS user Timing = LHCION1 (LHCION2 is reserved for the dedicated MD)

Contact Person: D. Manglunki

* Reminder:

- MDION is reserved for the nominal beam in the PS,

- LHCION is reserved for the early beam in the PS (with the previous CZERO of the PS, i.e. 1670 ms),

- MDPRO is reserved for the early beam with the new CZERO of the PS, i.e. 1670 + 65 = 1735 ms.

 

Wednesday 26/08 (08:00 - 16:00)

PS dedicated MD

 

Thursday 27/08 (08:00 - 18:00)

Instability studies at PS transition*

Beam conditions: PS user = MD3 and PSB user = TSTPS (ring 2)

Contact Person: S. Aumon

* These studies can also be performed in // in the following day / week (tbc) as a 2 BP cycle is reserved in the PS supercycle

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 = EARLY

SPS user Timing = LHCION1 (LHCION2 is reserved for the dedicated MD)

Contact Person: D. Manglunki

* We came back to LHCION

 

Friday 28/08 (08:00 - 12:00) - 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 = EARLY

SPS user Timing = LHCION1 (LHCION2 is reserved for the dedicated MD)

Contact Person: D. Manglunki

 

Friday 28/08 (12:00 - 18:00) - Test alternate LHC injections on LHCFAST

Beam conditions: SPS cycle = LHCFAST2, PS user = LHCPROBE and PSB user = LHCPROBE

Contact Person: V. Kain
