HAPPY NEW YEAR!

Let’s hope for a working CAL and for lots of lumi.

Unfortunately recently many problems – see later

ZEUS Week Padova 10/2004 TSS: CAL Overview and DQM 3

A loose collection of incidents

Took over from Michele Sunday 20/12/04. CAL in reasonably good shape with 295 bad

channels (calibration version 3852). However, problem in time offsets version – please

always stick to the calibration procedures as posted on the web!

21/12/04 10am: FEC v3855 (297/0) 21/21/04 1pm: power glitch! 21/12/04 5pm: BC update v3856 (428/7) 23/12/04: BC update (452/9) 27/12/04: FEC v3861 (282/1) … and then a few more problems appeared ;-(

A loose collection of incidents ctd’ 28/12/04 morning: CALDAQ (telamon) PC broken

Backup system for teucer/ajax Many DQM processes (HIP, cronjobs, …) Alessandro (with Kerstin and Ulf): Move everything to

menelaus (which is now also called caldaq/telamon – still problems with the names – you have to login to telamon).

By now everything seems to be back, but our HV monitoring and HIP histograms suffered for some time loss of about 300k events!

Various CQC runs with various problems R23 not filled (we had that before – TLT problem?) B22 HV off did not use a number of these runs for BC updates.

New Web Tools

Zmon online In analogy to DQMCOC on the web cal_check

procedure should become simpler for the oncall person

References not yet there Calibration version cgi script New SOS collection New page layout Timing history script with link HV history script with link Please give feedback on the web pages and

the tools.

ZEUS Week Padova 10/2004 TSS: CAL Overview and DQM 12

Important for all oncall persons:

Please stick to the procedures as defined on the web. Where the definition is not so clear I will try to improve very soon Most important: Before each FEC/ADC-to-volts

calibration or trimming: update the bad channels and really change to the new calibration versions after the BC update!!! Reason: Time structure of GAFs!

I will create new web pages for all possible actions with very detailed instructions: BC update ADC-to-volts calibration Trimming FEC FEC after an access
