  1. 13/02/2006 - 14/02/2006 Operational procedures Tasks and data flow overview Laser Monitoring

  2. 13/02/2006 - 14/02/2006 Sliding window analysis A range of runs is selected for a given SM ● Play Back the history ● Valid the readout ● TP analysis ● Analyzes of the history of channel’s responses Prepare the computation of the short term correction coefficients Laser Monitoring

  3. 13/02/2006 - 14/02/2006 Data Structure built for the sliding window analysis Retrieve all the reduced data from DB corresponding to the range of runs ● Distributed data (12 PC of the farm) ● Data integrity checked Master PC located in counting room Data organization: Xmonitor corrections 1) The data structure is a concatenation of reduced data for each run ● Laser shape parameters from the MATACQ ● Pulse shape parameters ● Response to Blue Laser ● Response to Infrared Laser ● Response to TP 2) Tables are built containing all the possible normalization ● for a given color ● for a given lmodN Laser Monitoring

  4. 13/02/2006 - 14/02/2006 Play Back the history The play back is performed on each PC of the monitoring farm ● Reduced data ● Log files (specific to each process executed on a PC) List of tasks: ● LookLaserShapeParProc ● LookPulseShapeParProc ● ValidLaserEventProc ● CorrectResponseLaserProc The play back doesn’t correspond to the processing reprocess from the converted data Laser Monitoring

  5. 13/02/2006 - 14/02/2006 Valid the Readout ● VROProc TP analysis ● LookTPmonitorProc ● CorrectTPEventProc Analyzes history of channel’s response ● LookmonitorProc ●LookPNmonitorProc 1) Detect zeros and fluctuations in the history of each channel 2) Detect oscillations with a 12h or 24h period (temperature) 3) Make a correction: ● Interpolation (without irradiations) ● Fit (In situ) Laser Monitoring

  6. 13/02/2006 - 14/02/2006 Follow-up (suivi) of the evolution of the ECAL Build R/R0 for blue and infrared Lasers Data structure: 1) For a given SM and lmodN 2) For a given normalization 3) Several blocks of ASCII data ● row: channel number ● first column: response to blue Laser ● third column: response to infrared Laser List of tasks: ● LookConstraintProc ● ValidCorrelationProc Laser Monitoring
