MSS Bypass Project
MSS Bypass Project – Impact Areas Project Completion Date July 16 th (Adding on additional PS3 work) Main Ring Road Closure and Power Outages Main Ring Road reduction at A1 (Restriction lifted on 7/16/13) Power off to A1, A2, & A3 (Last power outage will be 7/15/13) PS3 Power Outage July 17 th from 0800 – 1630 Work in manhole to prepare for further work about 1.5 weeks away.
MSS Bypass Project – Impact Areas Cont. CHL ~5 day outage/reduction (only house power available) Monday, June 24 th through Friday, June 28th Two 5 minute power outages needed Monday, June – 0735 (Completed) Friday, June – 0705 (Completed) Cable pulls and splices in PMH 210 Meson Two 15 minute outages one week apart Monday, June – 0715 (Completed) Monday, June – 0715 (Completed) Monday, June (Bonus MCC-2 MS3) Cable pulls and splices in PMH 110 Impacts MCC, Holometer, MW9, all enclosures, systems, and buildings
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 in ~1 week 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 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
