M800 Testing Model Assumptions

• Hybrids sent with PA bonded and the PA pulsing
  /thermal cycle tests performed
• Until module burn-in available, module production
  will be limited
• All modules will be burnt-in using Vienna box due
  to timing of rod delivery
• Full testing procedures available at
  hep.ucsb.edu/cmsUCSB/testproc.doc

M800 Testing Model (1)
Hybrids with PA bonded

• Quick Visual Inspection (on arrival)
• Hybrid Basic Test
• Setup self test, pedestal, noise, calibration
  pulse measurements
• Test requirements not finalized
• 3 minutes per test
• If pass, begin characterization test
• Hybrid Characterization
• Gain scan, pipeline scan
• New tests (No requirements, study unusual hybrids
  at first)
• 15 minutes per test
• Database entry of basic and characterization test
  results
• If there is a failure,
• If clear fault, we will repair part
• Otherwise send to experts for deeper study

M800 Testing Model (2)

• Module Basic Test
• Setup self test, IV, pedestal, noise,
  calibration injection, backplane pulsing and LED
  pinhole test
• Requirements still in flux
• Any problem modules quickly put into repair cycle
• 15 minutes per module
• Database entry for test results
• Storage until Vienna box available
• Module Burn-in (Vienna cold box)
• 24 hour Burn-in designed to determine failure
  rates/times
• Multiple thermal, electrical cycles
• Module basic tests pipeline and gain tests
• Database entry for long term and qualification
  tests
• Module Pinhole Test
• ARC LED pinhole test unless other simpler tests
  found to be sufficient

Production after M800

• Expected through-put matches anticipated peak
  production rate plus 33 contingency
• 12 modules/day per site
• 24 hybrids PA bonded/tested per day at UCSB
• Allows us to recover from unexpected shut-downs,
  schedule slippage, etc.
• Pitch adaptor wire bonding/testing will be done
  at UCSB
• Assumes every module is burnt-in using Vienna box
• Hopefully we will be able to shift to sampling
  only at some point
• To be determined using M800 production
• Rod assembly/burn-in testing model not completely
  fixed
• During rod assembly, modules will be tested upon
  insertion
• After gaining confidence, we will move to testing
  once full side is inserted
• Should be able to match 1.5 rods/day peak
