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
