1 Seog Oh/ Duke University/June, 2003 TRT/ ATLAS week at CERN Duke Production Status

2 Seog Oh/ Duke University/June, 2003 TRT/ ATLAS week at CERN Module Production  Mechanical Construction  All Type II (M2.01 to M2.37) are completed and gas tight.  All Type III (even number Type III (minus M3.32,M3.34)) are completed and gas tight.  Stringing  Type II  M2.33 and M2.34 are remaining to string.  Super spares (M2.35, M2.36, M2.37) will be strung by the end of September.  Type III  5 Modules were sent to Hampton for stringing  M3.16, and M3.30 are remaining to string. –Either Duke or Hampton will string  Super spares (M3.36) will be strung by the end of September.

5 Seog Oh/ Duke University/June, 2003 TRT/ ATLAS week at CERN  Duke Acceptance testing  Type II  M2.02, M2.03, M2.04…. M2.16 are completed including final gas leak test and signal test.  Type III (even)  M3.02, M3.04, M3.06… M3.14 are completed including final gas leak test and signal test.  8 Type II, and 6 Type III are at Hampton for gain mapping

6 Seog Oh/ Duke University/June, 2003 TRT/ ATLAS week at CERN Wire-joint production  Original estimation was ~65,000, but we are approaching ~100,000.  Original estimation was ~280/day, but we have been producing ~400/day or ~2000/week.  We have slowed down to ~ /week, which is still enough to meet the reduced stringing rate at the three sites.  After 34 modules of all three types were strung, the rate will be reduced to ~1000/week. Need ~6000 for super spares (35/36/37).  After 37 modules, plan is to produce ~1000 for re- work at CERN and ~2000 for reserve.  The wire-joint production should be over by the end of August.

7 Seog Oh/ Duke University/June, 2003 TRT/ ATLAS week at CERN Fuses Boxes  The design is completed and they are being machined. We should have them back by the end of June.  Production is 40 sets of each type module (240 fuse boxes).  We also need dummy fuse boxes for the other module side. These are being machined as well.  Plan to start the assembly in July.  Need fuse delivery schedule. We only have 100 pre- production fuses.  No good estimation for the production time yet.  Should we test fuses through random sampling?  Not in critical path

9 Seog Oh/ Duke University/June, 2003 TRT/ ATLAS week at CERN HV capacitors  Decision was made to go with NPO/850pf /2000 volts.  Passed initial testing.  Arcing test at 2000 volts – 50 capacitors  Neutron radiation test – 20 capacitors  Co 60 radiation test – 20 capacitors  HV soaking for two months at 2750 volts – 50 capacitors  A fixture to assemble 20,000 cap is being tested  ~500 will be made for the beam test  Final testing with the assembled capacitors  Full production should start in August and would take ~two month.  Long term HV soaking test (10 days at 2750 volts) would take ~six months.  Not in critical path
