Monday 23/05 - Tuesday 24/05

MD title: Dependence of fBCT on bunch length and position
Beam conditions: single bunch on flat MD1 cycle MD26_L7200_V1

PSB user = LHCINDIV
PS timing user = LHCINDIV
PS cycle = LHCINDIV
SPS user =
RF MMI target = MD1

Contact People: D. Belohrad, L Soby

Additional remarks: 10 acquisitions (averaging) per position = 400ms and that at ~ 10 different position -20mm to +20mm in 5mm steps. Measurements to be done also with different bunch lengths.

When possible, a couple of hours should be devoted to the following check: 

MD title: Transverse emittance measurements with 4 batches of 25ns beam
Beam conditions: 4 batches of 25ns beam with nominal intensity per bunch (1.2e11)
Cycle: LHCMD_25ns_2011_V1, 18bp

PSB user =   LHC_MD_A + LHC_MD_B
PS cycle = LHC25
PS timing user = MD6
SPS user = LHCMD1
RF MMI target = LHCMD3

Contact People: G. Rumolo, et al.

Additional remarks: simultaneous transverse emittance measurements in the PSB and PS are desirable
