4. 4 LS1 Activities  CALO closure Passive dosimeter installation done SPD ECAL HCAL Pascal Perret - LPC Clermont 26/11/2014

5. 5 LS1 Activities  CALO closure Preparation: Check of electrical control system performed by Laurent B. A bad contact identified in a connector … but it was ok! But problems time to time … (system not very reliable!) Cleaning of vis à bille done by Bruno et al. Problems during ECAL opening: « dust » preventing to open ECAL!

10. 10 TED RUN  Preparation hctell04 replaced http://lblogbook.cern.ch/Common+Spares/116 The Tell1 125 has been replaced by te tell1 117 (1-ORx). The problem of 125 is PP3 lbus: ====== LBit 20 of PP3_lbus_data (DAQL_data bit 4) seems to be bad! The whole lbus (including control signals) seems to be bad! Pascal Perret - LPC Clermont 26/11/2014

11. 11 TED RUN Pascal Perret - LPC Clermont 26/11/2014

12. 12 TED RUN  Or higher intensity during a short period … Pascal Perret - LPC Clermont 26/11/2014

13. 13 TED RUN  Smooth running TAE Pascal Perret - LPC Clermont 26/11/2014

14. 14 TED RUN  2 points to look at PS 1FE/VFE/MAPMT ? To check with cosmics data ECAL ERROR bank? Pascal Perret - LPC Clermont 26/11/2014

15. 15 LS1 Activities: LHCb  Maintenance MARATON water cooling circuit All done! The Maraton we gave to the e-pool to check connectors is back New water connectors The old one have been analysed (no news yet!) Actions to be discussed for the whole LHCb Maraton …  New SPECS: First tests done by Clara on ECHVA/C tomorrow. Is it ok?  To do: Calibration: cf Jean-François report We have to define our needs in terms of memory use, CPU time per events, etc. to discuss with online team Piquet training & DOCUMENTATION Pascal Perret - LPC Clermont 26/11/2014
