Week 43 -
Floating SPS MD
Wednesday 26/10/2011 in parallel with LHC operation
(24h)
Wednesday 08h00 - Wednesday 20h00
Supercycle:
fully dedicated MD (12 [I-LHC-SU + ZERO] PS cycles + 4 ZERO for filling=> 12*3bp
+ 4bp = 40 basic periods)
MD title:
Preparation to ions for LHC
Beam conditions:
Test on long flat bottom ion cycle
Cycle:
LEIR user = NOMINAL
PS user = I_LHC_SU:LHC_ION_Nominal
SPS user = LHCION1
RF MMI target = LHCION_NOM
Contact Person: T. Bohl, D. Manglunki, P.
Baudrenghien, U. Wehrle, W. Höfle
Additional remarks:
Wednesday 20h00 - Thursday 07h00
Supercycle:
2 possible supercycles proposed
→
1) total 30bp, made of
one long LHC 25ns MD cycle
(18bp) + two short MD1 cycles (6+6bp)
2) total 42bp, made of one short MD1 cycle (6bp) + two long LHC 25ns MD cycles
(18+18bp)

MD title: Tune
shift, impedance localization, emittance growth, longitudinal stability in
double RF, nonlinear optics measurements with single LHC-type bunch
Beam conditions:
single LHC-type bunch (from 1e10 to 3e11 ppb)
Cycles:
LHCMD_25ns_2011_V1 (18bp), LHCMD_25ns_Q20_2011_V1
(18bp), MD_26_L7200_Q20_V1
(6bp), MD_26_L7200_V1 (6bp)
PSB user (1)= LHCINDIV:LHCINDIV
PSB user (2)= MD4:LHCINDIV_high_intSPS_PSB
PS cycle (1) =
LHCINDIV:LHCINDIV
PS cycle (2) = MD8:?
SPS user (1) =
LHCMD1 or LHCMD3
RF MMI target (1) =
MD2
SPS user (2) =
MD1
RF MMI target (2) =
MD1
Contact People: T. Argyropoulos, H. Bartosik, N. Biancacci,
J. Müller-Esteban, B.
Salvant
Additional remarks: The cycles played in the SPS will be for Q20 or Q26 optics according to the requests from the MD users, however the two types of supercycles played must be only those outlined above
Thursday 07h00 - Thursday 08h00
