Off-line analysis

List of changes in Run parameter

Run number range : Event

• 23211 ... : accumulation trigger changed from 2-plane to 3-plane

: kept running with 3-plane accum trigger, all planes unmasked

• 23247 - 23258 : electron detector found with its threshold power supply at 'output off' [hclog]
• 23276 - 23280 : electron detector found with its threshold power supply at 'output off' [hclog]
• 23677 - 23765 : the laser cycle On:Off period was changed from regular 60:30 to 50:25
• 23766 - 23773 : beam off, calib input runs
• 23774 - 23835 : beam off, (LED linearity tests, DAQ tests etc)
• 23836 - 23913 : transverse regular running
• 23914 - 23926 : transverse running, I=75, edet trigger Gatewidth scan
• 23933 ... : regular longitudinal running , I = 180uA
• 23939 - 23945 : edet trigger gatewidth scan with changing trigger and mask conditions
• 23946 ... : back to 3-plane trigger, all planes including sick channels of plane-4 unmasked
• 24141 ... : changed slave firmware to 0x321B, master board firmware to 0xAA0D, has data for two PWTLs but 2nd one not working yet
• 24175 ... : masked off plane 2: strip 10 & 41; plane 3: strip 62
• 24141 - 24242 : we do not have event-mode and scaler data for this period, the address-mapping in header file wasn't correct
• 24242 ... : we now have data corresponding to two different PWTL
• 24296 : this was a regular beam run, but I had my chipscope plugged into the master board, so if this shows a non-standard result, it should be taken with a pinch of salt
• 24296 ... : updated master board firmware to 0xAA0E, in the previous revision, the accum trigger corresponding to PWTL2 was not clocked at the final output stage, hence those patterns where the overlap between multiple triggers was only one clock wide were lost.
• 24319 : changed the slave board firmware from 0x3219 to 0x321B. Now pldelay readout works
• 24328 ... : changed the 2 ribbon cables that connected slave-2's PWTL2 output to the master board. Now the length of this cable is same as those used in slave-1 and in PWTL1 trigger.
• 24581 - 24594 : PWTL scan at low current (60 uA)
• 24747 ... : flipper removed from laser, hence finite contribution from laser-"off" too; laser-on:off changed to 90:45 from 60:30
• List of runs for which a rootfile does not exist !:
  • 23253
  • 23449
• List of runs on which my regular analysis scripts are not working and needs individual attention (some signal may be missing)
  • 25509
  • 25483
• April 27, 2011 : Scalar banks added to the electron detector DAQ
