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 26 th ) 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 5 th. There will be a 20 minute outage to remove the backfeed after the surge arrestors are installed
MI Startup Activities (~1 Week) Turn on power supplies and establish ramps Establish 8 Gev beam Match MI8 line lattice with IPM Tune abort Gev Establish 120 Gev beam Smooth orbits up the ramp Tune abort 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
