#10457 High error fraction in TT error banks (from Presenter page /Shift/TT: Error banks)

Started at 2017-09-24 00:37. Severity: Report. 1 comments

2017-09-24 00:37 Timon Schmelzer There is a ~100% error fraction in TELL1 42 of the TT. The ST Piquet is informed and investigating

#10454 empty bin in TT cluster (from Presenter page /Shift/TT: Clusters)

Started at 2017-09-23 15:46. Severity: Report. 1 comments

2017-09-23 15:46 Luciano Libero Pappalardo There is a white bin in the TT cluster. Plot: "Cluster per port vs TELL1". The empty bin is around: (x=28, y=18). Called the ST piquet. He is checking and will call back.

2017-09-23 15:58 Luciano Libero Pappalardo There is an empy bin in the plot: "Cluster per port vs TELL1" with coordinates (29,48) The ST piquet is informed and will check.

MUON

#10156 M1 muon station (from Presenter page /Shift/MUON:4.Hit Density Maps M1-M2)

Started at 2017-08-14 03:45. Severity: Minor. 3 comments

2017-08-14 03:45 Meriem Boubdir The issue with the hole in the inner region of M1 station remains. Issue reported before under message ID 117004.
2017-08-14 10:43 Oleg Maev Unfortunately, we lost configuration on 8 FEBs in CMB M1AR2_16A3. Problem on the chamber side and we can't fix it without opening M1 station. Problem will be open up to the end of year.
2017-08-14 10:47 Oleg Maev Updated the problem report and changed 1 fields (Severity). 'Severity' changed from 'Report' to 'Minor'

L0

#10434 Errors in Hlt2 due to L0Muon (from Presenter page /Shift/L0MUON: Status)

2017-09-14 09:10 Dominik Stefan Mitzel Hlt2 is reporting a lot of errors due to problems L0Muon had in Run 198972

HLT

#10459 Error banks in HLT1 for VELo very high (from Presenter page /Shift/HLT: 2- Error Banks in HLT1)

Started at 2017-09-24 15:34. Severity: Report. 1 comments

2017-09-24 15:34 Luciano Libero Pappalardo The error banks in HLT1 for the VELO are very high: concentrated around/above 400 Hz (the reference is 130 Hz). The VELO piquet is informed. He does not see any real issue at the moment but will keep an eye.

#10458 Velo and TT Error Banks in HLT1 are above threshold (from Presenter page /Shift/HLT: 2- Error Banks in HLT1)

Started at 2017-09-24 14:19. Severity: Report. 1 comments

2017-09-24 14:19 Kevin Heinicke The Velo Error Banks rate in HLT1 is at 160 Hz, even peaking up to 200Hz for a short time. The Velo piquet is informed and will have a look. Also the TT Error Banks rate in HLT1 is at 40Hz (instead of the 10Hz threshold in the description). The TT piquet will have another look. (The L0 rate is currently at 1MHz)

#10456 VELO error banks in HLT1 (from Presenter page /Shift/HLT: 2- Error Banks in HLT1)

2017-09-23 16:36 Luciano Libero Pappalardo The frequency is flat arond 1-2 Hz,rather than 130 Hz. The VELO piquet has been informed.

TRACK

#10474 VELO Alignment: PV left-right for X shifted (from Presenter page /Shift/TRACK: Velo Alignment)
