Week 26 -
Long dedicated SPS MD
Monday 25/06/2012 during LHC
stop
Consigne for SPS MDs
Put this virtual event from CBCM Timing new table in
enabled on one cycle in the sequence.
SX.EA-SACQ-CTM (Exp Area-Start
Acq) (200 ms)
SX.EA-EACQ-CTM (Exp Area-End Acq ) (4400 ms)
Monday 08h00 - 11h00
Access in the SPS to
bring the electronics for pressure gauges into the tunnel
PS
MD title: PS injection kicker MD in normal
and short-circuited mode
Beam conditions:
25ns nominal beam and h=9 beam
PSB user = LHC_MD_A + LHC_MD_B, STAGISO + MD3(LHC_lowemt_H9_A +
LHC_lowemt_H9_B)
PS user = MD9, LHC_SU
(LHC_DB_50#32)
Contact People: R. Steerenberg
Additional remarks: while the MD uses the short-circuited mode of the kicker, the quality of the other beams is degraded
