All Experimenters ’ Meeting

This report outlines the current status of various components at the experimenters' meeting on July 29, 2013. Key topics include the commissioning of the Proton Source, RFQ Injector Line, Linac, and Booster operations. It also details ongoing tunnel work and associated vacuum issues. Additionally, power outages affecting PS3, feeder 46B, and ongoing surge arrestor replacements are highlighted. The report specifies future activities including MI startup, beam establishment, and tune-ups, anticipating additional work post-MI operations.

  1. July 29, 2013 All Experimenters’Meeting

  2. Startup 2013 Machine Status: • Proton Source Commissioning and Studies • RFQ Injector Line (RIL) • Linac • Booster • Main Injector • Trying to finish up tunnel work – vacuum issues TeV & Muon Rings – Partially available for tours with approval and appropriate training

  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 2nd @ 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 wait for delivery expected (Friday, July 26th) • Schedule a ~1 day KRS outage (not really an outage, we can’t run power supplies) to replace all surge arrestors on transformers T85 & T87. Looks like the week of August 5th. • There will be a 20 minute outage to remove the backfeed after the surge arrestors are installed

  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)  • Requires tunnel access (2x8 hrs) • Calibrate tune table • MI8 line lattice matching • Dedicated beam study • Extraction line tune up (NuMI) • 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

  7. Shutdown 2012 Schedules and Links: Schedule can be accessed from the Operations Home Page - Schedules -> Operations Schedule Direct link to schedule - http://www-ad.fnal.gov/ops/schedule.html
