Fall Shutdown Intensity Reduction PlanBegins Saturday, August 30

th @ 0800Main Injector will run $23 events instead of $2A events to NuMI (~80 KW reduction)Linac and Booster will meet program needsBNB should be unaffectedSeaQuest will go down from 4 turns to 3 turns.Beam off Friday, September 5th @ 0800Slide11

Wilson Hall OutagesLow ImpactTues

day, October 10thPower to Wilson Hall (Entire site except Main Injector, Muon Campus, and Village)From 0700-0730MSS off KRSS backfeedSlide15

Upcoming IssuesIn July 2015 we will need to power the entire site (except the village) off of Kautz

Road SubStation (KRSS) for a year while operatingA new Master SubStation (MSS) will be built beside the old oneWe have the capacity, but don’t know if we can run a Physics ProgramPossible noise on the lines

Expect some problems with the Proton Source

Planned on starting up from the shutdown with the site on KRSS to test

Gives us some time to address

problemsWe don’t know what impact it may have on the rest of the LabWill lights flicker?Will processes be sensitive to the Main Injector ramp?Slide16

When do we test?Met with FESS and AD Departments to discuss possible test dates and impacts to schedules

Met with Division/Section power representatives to confirm test dateLocked in a test starting date – Tuesday, November 4th

The duration of the test will depend on the results

If we can operate, stay on KRSS for some time to allow the Lab to cycle through its normal power usage. Look for an agreeable time to switch back.

If we cannot operate, switch back to using both substations after a few days, apply fixes, regroup, retest

Worked with FESS HV to put together a likely schedule for the rolling power outages across the lab while the power feeds are being configuredSlide17
