Remaining Schedule

• Data Taking Schedule
• CAL cosmic data taking started Saturday Sept. 27
• Data taking configuration is CAL_LO trigger,
  CAL_TACK60, TKR_TACK0
• 188 hrs of shifts scheduled for 75 livetime,
  expect 140 hrs x 30 Hz 15 million triggers
  (Sasha Chekhtman estimates 1000 good muons per
  3mm along each log in the central half)
• 1-day of High Energy Muon data with external
  trigger from Scintillator coincidence lead
  shield
• 2-days of Van Der Graaff data with nominal trigger

New TEM-PS test

• New TEM-PS was tested on EM CAL Mini-Tower
  system on Friday, Sept. 26
• Test data collected before, during, and after
  test is burned to CD-ROM and stored with work
  order
• NRL is studying test reports now (E. Grove)
• Basic results
• 15 increase in CAL pedestal width (I.e. noise)
• 0.6 increase in TKR threshold width (I.e. noise)

Summary and Plans

• Overall, a highly successful test series!
• Mechanical and electrical integration procedures
  developed and issues found
• Test scripts exercised and developed
• Team building for integration and test
• Integration facility operations exercised and
  developed
• Data to be collected will meet the requirements
  in the IT EM test plan
• Need a EM2 test series in February time frame
  mechanical, electrical, and software tests test
  plan proposal in progress
• Planning for EM2 tests should try to be as
  conservative as possible, I.e. provide as much
  test hardware as affordable and/or practical to
  manufacture
• Need to develop a well trained team of test
  operators for flight
