slide2
Team 1: installation, services...
  • Team 2: repairs
  • Team 3: ”routing the last 20 meters of cables”, USA15 connection, finger connections, LVPS insertion, DCS monitoring
  • Team 4: commissioning of superdrawers, take data using MobiDaq
team 5
Team 5
  • Led by Kerstin and Martina Hurwiz
  • Analyse ALL commissioning data as they come  team 5 shifts

(1am1pm Stockholm, 1pm1am Chicago)

e.g. 3 runs to check on Tuesday

2 long runs taken during

the week end.

  • In depth analysis of problems,

feedback to hardware folks

commissioning data
Commissioning data
  • Pedestal runs
  • Charge injection scan
  • Constant charge injection
  • LED/laser: light pulse injected into the PMT
  • Physics/cosmics
pedestal runs
Pedestal runs
  • Pedestal, noise,

coherent noise ...

Low and high freq. Noise (Kerstin)

Coherent noise: look at covarariance matrix for the 48 channels (Ulla)

single charge injection runs monocis
Single charge injection runs (”MonoCIS”)
  • Inject a defined and constant charge before the shaper, only done on the low gain (why?)
  • Find non responding (dead channels)
  • Check stability over time (long runs over the week end)
slide7
This run looks good!

Long run (60051) over the week end: problems in module C47 (Kerstin)

charge injection scan
Charge injection scan
  • Inject increasing charges into the shaper
  • Stuck bits,
  • Check linearity
  • Compute gains
  • Check pulse shapes
  • Reconstructed pulse height vs phase
outlook
Outlook
  • Increase productivity: efficient ways to look at commissioning runs for team 5 shifters
  • Define specific analyses and assign to various folks
  • Make available tools to be able to look at this data in new ways, access all relevant information (eg DCS)
