Time schedule
  • Present to Dec 2002 Civil Construction
  • Dec 2002 - Beneficial occupancy get into
    building and start installing things.
  • 6 mos. (June 2003) to install experimental
    apparatus cryo system safety systems liq H2
    filling system instrumentation
  • xxxx in Lab G
  • Beginnings Absorber inside Lab G magnet.
  • To be determined Does magnet move _at_ t0 or not?
    Open question.
  • Absorber either inside magnet or something
    similarly constraining.
  • Choice Fill w. somehting else besides liq H2.
  • 2nd absorber Japanese absorber queued but not in
    immediately.
  • 3 6 mos. for filling and experimenting (2
    absorbers)
  • deinstallation and installation schedule
    inefficiency due to cryo/Tevatron
  • (we are running parasitically wrt cryo systems)
  • Milestones 03 liq H2 filling systems
  • complete RF (805 MHz) in situ
  • FY04 Complete rest of RF, 201 MHz cavity
  • Testing RF at 201 MHz w/Absorber
  • Sept 04 Completed solenoid for 201 MHz cavity
  • FY05 Beam Installation (Sept 05)
  • Dec 2005 Full shakedown, RF Solenoid
    Absorber (201 MHz scenario)
