Presentation Transcript
current schedule
Current Schedule
  • 2-3 day shutdown scheduled to start Jan 18 (Wednesday) to upgrade BPM system and reinstall slits and fast Faraday cup.
  • Shutdown for H- upgrade scheduled to start Feb 6 (Monday).
  • Estimate 3-4 weeks to finish all upgrade mechanical work.
  • Lab shutdown still scheduled to start March 1.
  • Main injector quads may be reclaimed at the end of March.
  • New klystron scheduled to arrive in early spring.
bpm upgrade shutdown
BPM Upgrade Shutdown
  • Install buttons on all blanked off BPM ports.
  • Replace cavity wire scanner with a BPM.
  • Install new can for slit scanner and fast Faraday cup.

pre upgrade studies
Pre-upgrade Studies
  • Perform cavity phase scans using new BPM.
  • Tune cavities to specified amplitude and phases, and measure beam emittance using quadrupoles and slits.
  • Document final settings before H- shutdown.
more realistic schedule
More realistic (?) schedule
  • Feb 1st, H- source to alignment
    • Depends on how much time needed for alignment
      • Simply need to be early enough
  • Feb 3rd, last H+ run
  • Feb 6th, start removing H+ source
    • Mostly electrical first (cables and such), then mechanical (source and stand out)
  • Feb 16th, new stand installed
  • Feb 24th, H- source installed
    • Includes vacuum connected (may be not pumped down)
    • Includes all electrical connections
  • Feb 27th, alignment
  • Feb 28th, start commissioning
    • HV => Plasma => Beam

3 weeks

other hins shutdown activities
Other HINS Shutdown Activities
  • Waveguide distribution from klystron to test area will be removed. Klystron will only power beam line.
  • Modify klystron interlocks, to remove monitoring of RF test areas.
  • Complete documentation necessary for remote operation of facility.
  • LLRF work on vector modulator feed-forward.
h startup
H- Startup
  • Will start (hopefully) sometime in early March, contingent upon good vacuum, working power supplies, controls, and safety approval.
  • May need a week to optimize LEBT for best RFQ transmission.
  • Retune cavities for transmission to diagnostic line.
  • Measure emittance of new beam with slit scanner.
loss of mi quadrupoles
Loss of MI Quadrupoles
  • NOVA project will want the spare MI quads when they are ready to construct magnet girders.
  • Present commitment date is end of March.
  • This will render diagnostic line and Buncher 2 useless, but RF work and beam through Cavity 4 can continue.

These quads go

away.

other items during ad shutdown
Other Items During AD Shutdown
  • Complete 6-cavity test with vector modulator controls.
  • New klystron due to arrive in spring. Current plan is to swap out klystrons (will this require mech. support?).
  • Complete beam line design for 2.1MeV chopper test.
