From 08:00 to 11:00 there will be an intervention in the PS to repair a 80 MHz RF cavity
First MD: Injection losses on high-intensity beams
Beam conditions: PS user = CNGS and PSB user = CNGS
Contact Person: S. Aumon
Second MD: Depending on the advancement of pending issues related to the TSTLHC25/LHC25 beams, the subject will be:
1) Change h84 timing tree to counteract coupled-bunch oscillations recently observed on LHC25
Beam conditions: PS user = LHC25 and PSB user = LHC25A&B
PS user = TSTLHC25 and PSB user = LHC25A
PS user = TOF and PSB user = LHC25A&B
(with intensity for LHC 50 ns)
#bunches =12 - 72
No special requirements on intensity
Contact Person: H. Damerau
2) First test to produce TSTLHC25/LHC25 without SYNCDDSMHS
Beam conditions: PS user = TSTLHC25 and PSB user = LHC25A
#bunches =12 - 48
No special requirements on intensity
Comment: This MD affects all LHC multi-bunch beams
Contact Person: H. Damerau
3) Testing a modified MHS with an additional serial input
Beam conditions: PS user = TSTLHC25 and PSB user = LHC25A
#bunches =12 - 48
No special requirements on intensity
Comment: This MD affects all LHC multi-bunch beams and AD
Contact Person: H. Damerau
Remark: There should be beams delivered to the PS users most of the time.
