SCT DQshift

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

System effected SCT ald look for run.

2] Check the known defects in the database for this run:

Start at the ATLAS DQ homepage

Start at link Tier-0 offline

There is a finite number of defects defined for the SCT (twiki SCT DQ defect list)

3] Look at the histogram-summary from Tier-0 processing and sign-off the run:

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

a) look for known defects: 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.

Note:

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

b)

c) sign of the run

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)

4] Obtain information for run-summary

Get the run summary (report, lumi and efficiencies) from the SCT DQ webtool

Use SCT-standard and use the run-number

5] Finish up: Make an entry in the ATLAS e-Log

Enter the run summary and additional comments in the e-Log on the ATLAS operations page
