/global/data1a/gretina/Rm134Mar12: get confirmation from Heather

File Structure on GRETINA cluster

 Here offline decomp data gets stored:
  /global/data1a/gretina/user1
  /global/data1a/gretina/user2
  /global/data1a/gretina/user2_1
  /global/data1a/gretina/user4

Status 5/28/2012

Channels:

  • Q4P2ε1 - grounded in the detector
  • Q6P2ε3 - FET/preamp broken
  • Q7P3φ5 - gain 1/10 - broken wire or bad contact in the detector - to be further tested

Radial boxes:

  • SN 005207 - over current
  • SN 005222 - over current

Spares available: 3

Digitizers:

  • SN 067h - errors on bits 9 and 10 with rate >100 kHz
  • SN 02Eh - errors on bit 12 with rate ~4 kHz
  • SN 097h - the card is blowing the fuse for the 5V

Spares available: 1 (blue)
