LAT Horizontally

• First End2End runs are here
• LAT Horizontally
• This is how we will run at NRL!
• Important to understand what the data looks like
  before we ship the LAT!
• Half the runs with the VDG in parasitic mode
• No change in detector occupancy seen!
• Nor was it expected!
• Photon rate lt1 Hz in the LAT
• Run numbers
• All runs
• 077002680 - 07002682
• 077002685 - 077002714
• 077002716 - 077002736
• With VDG on
• 077002704 - 077002730
• Trigger rate
• About 290 Hz vs 520 Hz in the vertical position
• No periodic trigger yet!
• Cal configuration (thresholds)

You Don't Believe Me?

• The LAT was really flipped on its side

LAT Vertical

• LAT 70x preliminary runs
• New default run type
• 077002485 - 077002496
• 077002503 - 077002509
• 077002511 077002515
• LAT 71x preliminary runs
• New 'B10' i.e. Muon gain and 4-range readout of
  some trigger engines
• 077002457 - 077002465
• 077002497 077002502
• Hardware configuration
• 'x' in 70x and 71x represents which parts of the
  LAT that are on'
• Which EPUs, primary or redundant GASU etc
• Will post a list of the different hardware
  configurations on the IA page
• But you shouldn't worry about which EPU processed
  your event!
• Cal configuration (thresholds)
• Updated from January
• No more hot LACs!
• In the runs database
• Both of these configurations appear as 'intSeApp'
  (Script name) and have no End2End ID.

LAT Vertical End2End Runs

• End2End runs
• Starting on Monday!
• Will run 12 nights
• Plan is for a total of 48h of data
• Run length changed
• To maximize efficiency
• 30 minute runs
• 1M events/run
• File size estimates
• Merit ntuple 450 MB
• SVAC ntuple 1.7 GB
• Digi 600 MB
• CalTuple 375 MB
• Recon 9 GB
• We will process the data as it comes in.
• Will keep an updated list of 'Good' runs on the
  web.
