1. ATLAS Tile Calorimeter Data Quality Assessment and Performance
with Calibration,Cosmic and First Beam Data.
Offline
Shifter tools:
-The Online Histogram
Presenter (OHP) is the ATLAS tool
to display Histograms produced by
the online monitoring system
Online
- Monitoring of the physics
performance of the detector, integrated
in ATLAS-wide monitoring and DQMF.
Offline Monitoring/DQ is called Tier0 DQ.
Tile Calorimeter Data
Quality Infrastructure
We study the data and
provide a first feedback
Online Monitoring: Average cell energy
vs module for EBC partition.
-Online ATLAS event displays and
Data Quality Monitoring Framework
(DQMF) perform automatic checks
to assess Data Quality .

We update the detector conditions before the bulk reconstruction starts.
- The detector status is also evaluated in calibration runs:CAF Monitoring/DQ (Calibration streams):
Tool to update the bad channel list

2. Tile Calorimeter Performance with calibration, cosmic rays
and LHC single beam data
-During 2008, the Tile Calorimeter was commissioned with the other ATLAS sub-detectors.
-Cosmic data was analyzed to verify the Data Preparation.
-The commissioning culminated when the Large Hadronic Collider (LHC) circulated proton beams .
Energy response
Noise
ATLAS preliminary
8-fold structure in phi of the beam splash events. The structure and the up-down asymmetry are due to the material in front of TileCal. Effect observed in OHP Monitoring during the shift.
Electronic Noise as a function of time from the start of ATLAS continuous running in Aug to Nov. 2008
The relative variation in time is within 1%.
ATLAS preliminary
Timing
TileCal work in progress.
Measure of the timing inter-calibration with splash events.
Within each partition, an almost flat distribution was observed, demonstrating the very good time equalization
performed with laser data, as of the first beam date.
Direct correlation between cosmic results and beam results. Cosmic cell time response vs beam cell time response both referenced to the time of one channel.
