Shift Summary entries in the logbook

19 October 14:23 Sean Benson LHC:
BCS Beams

LHCb:
Largely happy, the known Velo warnings are still there though are expected to be fixed between fills.

To be done:
Collect.
19 October 22:33 Zhukov Valery LHC: physics fill 6308 dumped 14:39
physics fill 6309 from 17:17 dumped 18:18
physics fill 6311 from 22:29 run200779

LHCb:
-VELOC cooling alarms are gone, see https://lblogbook.cern.ch/Shift/123757
some err. during ramping-closure from thr. tuning.
-MUON lost in RC(dead) after ECS-MUSIDES err, piquet called, recovered
-RICH2 multiple local tests by piquet
-TT RC errors, autopilot recovered

To be done:
collect data
20 October 06:29 Sergey Barsuk LHC:
- fill 6311 in stable beams since 22h25, recorded by now 9 pb-1 with efficiency 93%.

- reached 6.5 fb-1 of recorded total integrated luminosity:
***************** https://lblogbook.cern.ch/Shift/123785
***************** https://lblogbook.cern.ch/Shift/123784

LHCb:
- very smooth data taking.
- OT: several error-banks and SEU error messages.
- TMUON: several optical links errors, disappearing rapidly from the alarm screen.
- TT: few desynchronization errors.
- Calo: few desynchronization errors.


To be done:
- enjoy the remaining part of the fill.

Run Chief : Barbara Sciascia

VELO Piquet : Francesco Dettori

Name Report
19 Oct 18:48:24 Francesco Dettori Cooling still under investigation (https://lblogbook.cern.ch/VELO/14212).
IV scan to be taken.

ST Piquet : Vincenzo Battista

Name Report
20 October 00:15 Vincenzo Battista Few IT/TT HV channel alert limits increased.
TT front-ends went into error during configuration. Few reset/reconfigure iterations were needed to fix that.
This is a known issue (more details here: https://lblogbook.cern.ch/ST/5344)

OT Piquet :

Name Report
20 October 09:26 Patrick Mackowiak All ok, t0 calibration is running again

RICH Piquet : Konstantin Gizdov

Name Report
20 October 09:20 Konstantin Gizdov Nothing to report

Calo Piquet : Maximilien Chefdeville

Name Report
20 October 09:13 Maximilien Chefdeville Calo is OK.

Muon Piquet : Marco Santimaria

Name Report
20 October 09:19 Marco Santimaria - M3C32B_GAPD tripped, now recovered -> https://lblogbook.cern.ch/MUON/6659
- crash of muecs01, restarted in few minutes by the online piquet -> https://lblogbook.cern.ch/MUON/6660

HERSCHEL Piquet : Heinrich Schindler

Name Report
20 October 09:25 Heinrich Schindler Ok.

L0 Piquet : Francesco Polci

Name Report
20 October 09:28 francesco polci All ok.

Checked runs 200749 -> 200794

- runs 200749 -> 200793 : all ok
- run 200794: new hot region top right (see emulator comparison plot attached), but it looks transient, since it
is not present in runs before nor in the current run.

HLT Piquet : Maarten Van Veghel

Name Report
20 October 09:24 Maarten van Veghel Nothing to report
HLT1 disk occupancy HLT2 output rate

Alignment Piquet : Maxime Adrien Schubiger

Name Report
20 October 09:31 Maxime Schubiger Nothing to report

Online Piquet : Luis Granado Cardoso

Data Quality Piquet : Fabio Ferrari
