  1. August 05, 2013 All Experimenters’Meeting

  2. Startup 2013 Machine Status: • Proton Source Commissioning and Studies • RFQ Injector Line (RIL) • Linac • Booster • Main Injector • Startup and Tuning

  3. Power Outages • PS3 Power Outage • Oil Switch Replacement • Impacts PS3, PW5, & PC3 • Run on generator for ~1 week • Connect generator Monday, July 29th @ 0800 – 1000 • Disconnect generator Friday, August 9th @ 0800-1000

  4. Power Failures • Feeder 46B • Wednesday, July 24th @ 2142 • Impact – Possible F0 ventilation system • Fault located between P71 & F4 • Further isolation and repairs necessary

  5. Kautz Road SubStation • Status • MI backfed from Master SubStation • Using Feeder 45 for MI conventional power which is normally T85 on KRS • We ordered 6+ new surge arrestors (4.7k each) from Hubbell and they were delivered on Friday, July 26th • Schedule: (Weather Dependent) • Monday, August 5th replace T85 surge arrestors • No machine impact (In Progress) • Tuesday, August 6th replace T87 surge arrestors • No beam during work 8-10 hours • After replacement, test both T85 and T87 • There will be a 20 minute MI conventional power outage to remove the backfeed, not scheduled.

  6. MI Startup Activities (~1 Week) • Turn on power supplies and establish ramps • Establish 8 Gevbeam • Match MI8 line lattice with IPM • Tune abort line @8 Gev • Establish 120 Gevbeam • Smooth orbits up the ramp • Tune abort line @ 120 Gev • High field Orbit smoothing (quad moves) (Have data for 1st) • Requires tunnel access (2x8 hrs) • Calibrate tune table • MI8 line lattice matching (1st of 2 passes complete) • Dedicated beam study • Extraction line tune up (NuMI) (Attempting extraction) • Tune up for operation • Deliver low intensity beam to NuMI beam line for target scans • Estimated to take an additional week after MI is tuned up for operations
