--- Minutes ---

Operations

  • During weekends, there were order of ten 100% deadtime due to EMC/EMT/DIRC/ODF. All cleared by starting a new run.
  • We planned to power off all the crate today after operations meeting, but we changed __not__ to power off for a while, since IFR people want to take cosmics for next few weeks.

EMT

  • Run 76397 has warm EMT tower not associated with hot EMC tower (e-logbook entry, look for [03:35]). It disappeared in new run and never came back. The cause is unclear, maybe EMC UPC, maybe TPB? We will keep an eye on it when we start to take data.

DCT

GLT

Online

  • Before Run7 begins, we need to check if newest tag is being used.

L3

  • Arik's Track fixup validation is still on-going. tcstage is not working currently.
  • Su Dong and Selina will do some R&D work on L3 EMT filter.

DQM

Trickle injection monitoring

Trigger Configuration

  • At the end of Run7, they plan to burn the detectors down to acheive highest delivered luminosity. We need to prepare for factor 2~3 trigger rate. Current emergency configuration which reduces 35% is not enough.

AOB

  • We will have another meeting next week, and then we'll go into every other week mode.
  • Rainer prepared a plot, but we forgot to call in! Sorry Rainer.
  • Many thanks to Debbie for her hard work for a year!
