Status of the electronic integration in FfM

1
Status of the electronic integration in FfM

• 10.8.2007

2
Status

• Finished SM3
• Last chambers will be shipped to MS next Week
• 2.5 Technicians (Werner Amend, Arnold
  Wiesenäcker, Hannelore Hinke)
• 1 Diploma Student (Andreas Fick)
• 2 PhD Students (Konstatin Antipin, Frederick
  Kramer)
• 1 Postdoc (Matthias Hartig)
• 6 Students (wissenschaftliche Hilfskräfte)
• Support from outside (Benjamin Doenigus)

3
Step1 ROB Mounting

• Well established procedure
• Done by students (wissenschaftliche Hilfskräfte)
• 2 students 2-3 h per chamber
• Rate 1 chamber per day
• (max. 4 chambers per day)
• gt No delay expected

4
Step 2 First Electronic Test

• Starting the production phase
• 2 Setups for testing
• Max Rate 2 tests per day
• Digital Tests 1 h (can
  run in parallel)
• Noise/Pulser Tests 1 h
• Stress Test 12 h (can
  run in parallel)
• gt 1 test / setup / day

5
Step 3Gluing of Cooling pipes

• Done by two technician and a students
  (wissenschaftliche
• Hilfskräfte)
• 1 h 1.5 h preparation and gluing for 2 persons
• 12 h hardening
• Rate 1 chamber per day
• (max. 2 chambers per day)
• Caused no delay so far
• Changing production labs
• gt Gain only a little by improved
  production process

6
Step 4 Second Electronic Test

• Same setup like for first test
• 2 Setups for testing
• Max Rate 2 tests per day
• Digital Tests 1 h (can
  run in parallel)
• Noise/Pulser Tests 1 h
• Stress Test 12 h (can
  run in parallel)
• gt 1 test / setup / day
• gt max. rate 1 chamber/day

7
Production Rate per Week

• Production of 1 Layer per week
• gt 10 tests a week
• For SM3
• Rate lt 10
• 2-3 chambers needed more than one 2nd test
• Last 4 Layers
• 4 Memory errors
• 2 NI test errors
• Problems with initialization (?)
• 6 stress test failures (?)
• Broken Cable Bridges

8
Improvement

• 7.5 broken Cable bridges gt bridges are tested
• MCM ID gt solved by Tom
• 3rd test stand gt in preparation

Next Steps

• Update of software CommandCoder, DCS
  firmware, InterComLayer,
• feeserver,
  
• Alexandru agreed to take over this task. He
  needs support gt Meet
• after the Status Meeting
• gt Is needed for new PVSS Test Software
  (Andreas)
• gt Test can be done by Students

• BUT we need more manpower gt Martin
  Freudenberger will help us
• Evaluate test results skip long stress test
  with cooling pipes (?)
• (Another production site)
• ???
