Status overviewStatus overview

Detector status, OCDB files: List of active modules vs time Handling single dead/inefficient pixels for MC

Quality assurance issues: Raw-QA histos for the DQM Raw-QA checkers implemented

Geometry and other issues: Update in the forward region (Mario’s talk) Update of the “ideal” sector geometry (Andrea et al.) Trackleter:

- Updates for tracks+tracklets multiplicity estimation (Ruben)

- Include inner layer cluster labels in ESD (Mariella, ongoing)

ClusterFinder (HLT version to be checked)

Active half-staves vs timeActive half-staves vs time

… as yesterday -> Total : 96 Inner Layer : 28/40 Outer Layer : 68/80

Raw OCDB OK for all LHC periodsOnly problem found with run119926 (1 more HS to be masked)

Handling dead pixels for MCHandling dead pixels for MC

A procedure has been defined to determine “bad pixels” (= dead + inefficient)

Checks on stability over LHC10 periods (b,c,d) ongoing

Statistics needed synchronization with MC productions

Further remarks : ITS/Calib/SPDDead object: both inactive HS and dead pixels

For MC: ITS/Calib/SPDNoisy contains dead pixels as found in December 2009

Introduction of a new OCDB object to be discussed

DQM plots and Raw-QA checkerDQM plots and Raw-QA checker Plot list:

o Data format errors (20 error types per 20 Eq)o Chips showing MEB (1200 chips)o 2 Hitmaps (Inner and Outer layer) o FastOr bit map (1200 chips)o FastOr bit correlation (Inner vs Outer)

Updated labels of the histograms: [communication between DQM shifter and SPD experts]

Offline QA Checker sets FATAL bit for RAW task: at least one Data Format error occurs at least one chip is suspected to show the MEB

Geometry in the fwd region Geometry in the fwd region

What was needed: improve description of cabling and services, mainly affecting the forward region (||>1.5) triggered by inconsistencies found in the FMD data analysis (more background than expected from MC)

Corresponding actions: detailed checks: drawings vs actual implementation few issues identified:

- material to be revised / added- completely missing parts (mostly minor details)

corresponding code implementation :- most of it (relevant parts) already done (Alberto and Mario)- committed to svn, available for tests- couple of last details will go in within this week
