L1CTT status Crate x13 and x14

L1CTT status (Crate x13 and x14)

• Running fine over the Weekday
• Read out data from 5 VRBs (CTOC, CTTT, and STSX)
• Some problems on weekends
• Saturday morning (Store 2684)
• x13 went FEB, Fix x13, init VRBC did not help
• Took x13 out from global run
• Left 2 STSX VRBs out of read out and put x13 back
  in the global run
• Saturday night
• Put 2 VRBs back to global run during zero_bias is
  running
• Saturday midnight to Sunday morning (Store2686)
• CTTT behaved badly
• 5 boards lost their configuration
• x13 went FEB again, when physics run started
• Took x13 out from global run during
• CTT A/O rates went high, because a CTOC board
  behaved badly
• One or two physics runs kept collecting data with
  wrong TTK bits
• run178120 or 178121 or both??

L1CTT status (Crate x13 and x14)

• Sunday Evening (Store 2689)
• Left 2 STSX VRBs out of read out and put x13 back
  to global run again
• To CFT shifters
• Read CTT instruction page, when your shift is
  started
• http//www-d0online.fnal.gov/www/groups/cft/CTT/o
  nline/Instructions/instructions.html
• Keep checking DAQmon, dfe_ware, and ctt_examine,
  etc
• Enter CTT checklist at the begin of the store,
  for each physics run, and when you get any
  troubles
• Most of them must be done, even when x13 is out
  of global run

L1CTT Status (Firmware and others)

• Firmware
• DFEA firmware v014 with new track equations was
  initialized
• Found L1CPS bits in the DFEA
• Debugging STSX/STOV and CTQD with data dump
• ctt_examine
• Added L1CPS plots
• Will add more plots
• Understanding basic CTT performance
• L1 Track efficiency independent of offline
  tracking, using Z -gt ee samples reconstructed by
  only EM and CPS
• L1 Track (w/ L1 cluster) efficiency w.r.t offline
  tracks (w/ offline cluster)
• L1 Fake rates w.r.t offline tracks
