SPS MDs

Monday 16/05 - Wednesday 18/05

MD title: Working point scan and emittance evolution studies on a Q20 flat cycle. Comparison with a Q26 cycle
Beam conditions: single bunch with intensity per bunch up to 3.5e11 on MD_26_L7200_Q20_V1 or MD_26_L7200_V1 cycle

PSB user = MD4
PS timing user = LHCINDIV
PS cycle = LHCINDIV
SPS user = MD1
RF MMI target = MD1

Contact People: H. Bartosik, Y. Papaphilippou, B. Salvant, BE/OP, BE/RF

Additional remarks: transverse emittance measurements along the cycle in the PS are performed in parallel by E. Benedetto

Wednesday 18/05

MD title: Longitudinal instabilities at flat top with radial steering
Beam conditions: two bunches, first nominal and second with variable intensity on LHC_INDIV_2011_V1

PSB user = LHCINDIV + LHCPROBE, LHCINDIV x2, LHCINDIV + MD4
PS timing user = LHCINDIV
PS cycle = LHCINDIV
SPS user = LHC4
RF MMI target = LHCMONO

Contact People: T. Bohl

Additional remarks: the intensity of the second bunch is changed by changing the PSB user (LHCPROBE for a second bunch with very little intensity and MD4 to scan the range between LHCPROBE and nominal LHCINDIV)

Thursday 19/05

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

Friday 20/05

Beam conditions: single bunch with intensity per bunch up to 3.5e11 on MD_26_L7200_Q20_V1 or MD_26_L7200_V1 cycle

PSB user = MD4
PS timing user = LHCINDIV
PS cycle = LHCINDIV
SPS user = MD1
RF MMI target = MD1

Contact People: H. Bartosik, Y. Papaphilippou, B. Salvant, BE/OP, BE/RF

Additional remarks: transverse emittance measurements along the cycle in the PS are performed in parallel by E. Benedetto

PS cycle = LIU_V1

Contact People: A. Findlay, H. Damerau, S. Hancock

Additional remarks:
