stop
Monday 08h00 - 16h00
Supercycle:
fully dedicated MD (26 bp)

(26bp),
MD_25.92_55_270_Q20_2009_V1
(26bp)
PSB user = LHC_A, LHCINDIV
PS user = MD6, LHCINDIV
SPS user =
LHCMD2 (pulsed), COAST2 (coast)
RF MMI target = MD1
Contact People: S. Cettour-Cave, T. Bohl, BE/OP, BE/RF
Additional remarks:
Monday 16h00 - 21h00
Supercycle:

MD title:
Emittance growth in coast for crab
cavity studies
Beam conditions:
single bunch with variable intensity (1e10 to 1.2e11) to be coasted at 270 GeV/c
on Q20 optics
Cycle:
MD_25.92_55_270_Q20_2009_V1
(26bp)

Contact People: R. Calaga, E. Métral, R. Tomás, F. Zimmermann
Additional remarks:
Monday 21h00 - 22h00
Supercycle:
SFTPRO-like cycle + two (or more) CNGS without beam
MD title:
Switch to
the new supercycle with the MD version of SFTPRO
Beam conditions:
low intensity SFTPRO-like beam (1 to 2e12 p), only one batch injection into the
SPS
Cycle: SFT_LONG_L9690_2010_MD_V1
Contact People: BE/OP, BE/RF
Additional remarks: no RF gymnastics before the extraction. Voltage before extraction should be reduced as well to minimize the Dp/p during extraction and get max resolution for following dispersion measurement.

Contact Person: O. Hans, S. Gilardoni, R.

Additional remarks: Beam to the East area will have to be stopped during this MD, because special settings of the extraction elements are required, which are not PPM

two long flat
bottom LHC cycles, one nominal optics and the other one low gamma transition
MD title: Optimization of the 25ns beam on

Contact People: Eduardo Nebot Del Busto, Bernd
Dehning
Additional remarks: This MD will be carried out in parallel with the SPS users (see next) and PS (and PSB? compatibility to be checked) physics users. During these tests it has be made sure that only this beam goes to the beam dump, therefore the other users must have either PS (or ISOLDE?) as destination and have zero cycles in spare.
Friday 19h00 - 20h00
Change of supercycle from LHCMD_25ns_2011_V1 (18bp) + LHCMD_25ns_Q20_2011_V1 (18bp) to MD_25.92_55_270_2009_V1 (26bp)
