On-line Data Quality Monitoring for the TPC

• Klaus Schossmaier
• CERN PH-AID
• ALICE TPC Electronics Meeting
• CERN
• 13 14 January 2005

Outline

• DAQ architecture for the TPC pre-commissioning
• Monitoring schemes
• Software architecture of monitors based on DATE
• Raw data format
• Monitors
• Hex-dump eventDump, mooDump
• Stand-alone Rolands monitor
• Framework MOOD

MOOD

• MOOD Monitor Of On-line Data and Detector
  Debugger based on ROOT
• Web page aldwww.cern.ch/MOOD
• Release MOOD v3-46c.tgz (RH 7.3, SLC3)
• Development and support Istanbul Univ. by Özgür
  Çobanoglu and Ferhat Özok
• Modules for several ALICE detectors exit and have
  been used during test beams
• Hex-dump utility mooDump
• Open issues concerning the TPC
• Difficulties to decode the RCU data
• Incomplete mapping information for the display
• Responsible person on the TPC side

Summary

• DAQ Software
• SLC3
• DATE v5 ? Tutorial 1415 March 2005 ?
• DATE library for on-line/off-line monitoring
• Rolands monitor
• Dedicated to the TPC detector
• Single person development/support
• Working well for display and analysis
• MOOD
• Framework for all detectors
• Development/support by an institut
• MOOD modules exist/used for several detectors
• Open issues ? need a person for the TPC module
• Aim to use it for the Hall 167 setup and for
  pre-commissioning
