FNAL LT Testing Status

• Modules 30200020008325 8345, 8425-8434,
  8413-8422
• were tested during June 9 June 13.
• We did 4 runs.
• K-Mux errors were happening two times only in
  the beginning of new run, program had to be
  restarted
• Quick connect between hose and coldbox was
  damaged and leaking. Replaced quick connect and
  renewed the liquid delay in one run.
• Module 8348 had high leakage current
  (2.8uA_at_450V) and steeper then usual.
• Modules 8331, 8336-8345, 8431 had high noise in
  the cold record (3.5ADC) -gt all channels
  marked NOISY -gt xml -1
• Possible reason no HV bias during cold cycle.
  Need more quiet time to investigate.
• Backlog 54 modules
