1. RECENT CAL PROBLEMS (including DQM person confusions) and DQM SHIFT TODO REMINDER T. Schörner-Sadenius Hamburg University CAL Meeting, 11 January 2005

2. CAL Meeting 13/10/20042 RECENT PROBLEMS and QUESTIONS Most required actions from TSS/Wladimir/Alessandro.  Keep in mind: Up-to-date SOS-page reachable from CAL home page. Look first there, then call (especially in the night).  We will soon have check lists for all actions (see last slide). Use them!  Problems  No change_version after time offsets measurement after access  confusion.  Dying menelaus PC  actions from AP,Kerstin, Ulf, …  Dying AJAX disk  v3876 could not be used in global/local  running for some time with bad calibration; took some hours to sort problem out.  always install new version after calibration and take local run with it!  B22 and B21 HV off  mostly solved by instruction crew on phone.  CAL timing shifted by ~50ns in GSLT and TLT histos  CFLTP cable.  RCO: “GSLT<>DC off sync”, GSLT.DC.MISMATCH in logfile  CFLTP cable.  RCO: “GFLT: component CAL keeping busy”  CFLTP cable  Various power glitches  switch everything back on!  Please make use of ALL CAL_QUICK_CALIB runs that are there and install (newcalconv, change_version, change_version_main) the derived calibration versions in chronological order!

3. CAL Meeting 13/10/20043 TODO SHIFT PERSON We want to calibrate as often as possible!  Morning:  Read elog book entries. Anything unusual during the night? Magnets off? In doubt call TSS.  Phone shift crew to find out about HERA plans. We need bad channel update every day. ADC2VOLT and FEC at least once a week.  Check last night’s DQMCOC histos on the web presenter.  Check the newly reconstructed runs in zmon (web or cal_check).  Check ping page.  Daily:  Take check-out runs using auto_checkout.sh.  Bad channel update using auto_badchannel.sh.  Uno scale factors using unocomp and updateUno.  Take an SRTDFLT checkout run.  Stay tuned to HERA conditions (RCO viewer): calibration possibilities?  Evening:  Check DQMCOC histograms for the runs of the day.  Check ping page. } Mail to TSS: Significant news?

4. CAL Meeting 13/10/20044 TODO SHIFT PERSON We want to calibrate as often as possible!  Every week (at least):  Do an auto_adc2volt.sh.  Do a full calibration using auto_fec.sh.  Do a trimming (using `trimming’ in caw on teucer).  Attend the components’ meeting on Monday at 11.  Give your weekly shift report in the CAL Wednesday meetings. Please bring always a bit more than just naked numbers – we should try to make this an opportunity for education!  After an access / after magnets off:  After an access or after the magnets were off we need a full calibration (after an access including DU offsets and time offsets – only in presence of coordinator)!  Especially the DU offsets with the required access to the HV and the complete lowering of the HV of all modules is critical. } Mail to TSS: Significant news?

5. CAL Meeting 13/10/20045 TODO SHIFT PERSON We want to calibrate as often as possible!  Always:  Carry the mobile phone and answer to calls immediately.  Inform TSS if problems / questions.  Read web pages and keep yourself and your colleagues informed of what is going on:  CAL generals  HERA and ZEUS status.  Tell TSS if non-trivial problems; we will put them on our SOS-CAL page.  Log your actions in our web tool (until we have better means) and, if relevant for ZEUS, in the electronic log book.
