The minimal path through all documentation necessary for an SCT DQ shift

Goal of the shift: make sure all flags related to SCT operation are correctly stored in the database before the run is processed at the Tier-1's


General information

The Official SCT DQ shift twiki

The ATLAS data quality portal

The ATLAS detector operations page


The DQ shift


The shifter checks if the known problems are indeed present, checks for potential new ones, signs off the run and makes a summary following these steps:


1] Check the ATLAs e-Log page for (SCT-specific) information on the run

Use search form on the ATLAS e-Log page

Check on system effected SCT ald look for run


2] Look at the histogram-summary from Tier-0 processing

This is the step where the real work is done: see if you can identify the known defects, look for potential new problems and 'sign off' the run.

Start at the ATLAS DQ homepage

a) Click on Tier-0 offline and select run you want and click on 'express express' stream.

   Note: if the run has *** , the run is still processing. You'll have to wait

b) click on defect database to check known defects:

   Use 'filter SCT'  and look for defects. 
   You will need to confirm these and look for new ones. There is a finite number of defects defined for the SCT. A full list can be found here: (twiki SCT DQ defect list). Each defect has a fatality-level attached to it.


c) click on entire run and check all histograms

   Now, check in the histograms if you understand the defects and if there are more/less than in the 'known database' database/Check if the defects are
       Check ID->SCT and things that are not ok.
       Note: write down efficiencies for later use (endcap-A, Barrel and endcap-C)

Look at the ES1 (express express stream pass 1) of the Tier-0 processing and check the atlasdqmhistogram-summary.

Note:

  • check box UNCHECKED (to indicated you have actually looked at the run)
  • password to sign-off the run: SctDq

c) new things: upload new entry what to do when you discover a new defect: Send a mail to the expert. Get the name of the shifter from the ATALS OTP page (xxx missing xxx)

d) sign off the run

    make comment and submit


4] Obtain information for run-summary

4a) Get the run summary (report, lumi and efficiencies) from the ATLAS DQ website

Click on 'report' for your run. This you need to copy-paste in the ATLAS e-LOg at step 5]

4b) get luminosity

     Start at ATLAS DQ homepage and click on your run that appears in the banner at the top of the page. (you might want to add 'and LHC' in the search string)


5] Finish up: make an entry in the ATLAS DQ logbook and e-Log

Start at the ATLAS DQ homepage

a) Click on DQ logbook

   Small entry

b) ATLAS e-Log Enter the run summary you got at step 4] and additional comments in the e-Log. Follow link 'bla' from the ATLAS DQ homepage

enter 'SCT'

title: SCT DQ report run <>

copy in the comment lines: - the 'report' you got from step 4] - the efficiencies you got from step 2]
