Cosmic Ray run (Milestone 3 - June 4) 14 MDT chambers 1 trigger sector (TGC) First display of an endcap cosmic ray track Kevin Black Muon Spectrometer Integration -- DOE site visit 2007 -- Joao Guimaraes 10
Lessons from M3 (MDT Monitoring) • Data storage problems (slow access to tape) • Trigger prescaled (~60) due to data writing speed!! • Lack of calibrations available for online and offline studies • Official procedure very slow (month) -- offline calibration centers • Srivas calibrated with online data --> FAST • Detector and data quality monitoring • High level monitoring (offline, tracks) }Flying • Low level monitoring (DAQ crate level) blind • Barrel MDT run for one week with wrong timing! Decided to help with MDT Online Monitoring Michael Kagan Shulamit Moed Provide fast data quality feedback of muon system (both endcap and barrel) See Shulamit’s talk for details Muon Spectrometer Integration -- DOE site visit 2007 -- Joao Guimaraes 11
