Friday 5/1/ meeting

I wish to lock in the power outage onTuesday 5/5/09 at the end of the 0930 lab scheduling meeting speak now or :

Parts and pieces: All equipment must be vacuum certified before these parts go into tunnel, we are currently missing. Mi 52 & electron cloud and micro wave absorbers (late July early August) One crystal collametor Tev. Possibly but tight Replace hadron monitor in minos absorber hall in Install 7 new kickers in Mi tunnel Mi 8 multi wires internal parts 1 st week of June. Numi multi wires

-Current electronic work list has 311 items in it. -I will show at a later meeting Cryo, EE support, controls, RF, instrumentation and Rad safety tests. - No jobs accepted after May 15 th. Meaning the shutdown lists need to be decided on. -All long shut down jobs need to be in the electronic work list( long shuddown). If they are in the short shutdown list you will need to move them over.

31 work days to the shutdown 46 calandar days to the shutdown

Linac Tank 5 Drift tube replacement( 10 days) over 5 weeks. Dump work vacuum leak checking ~6 days maintentance Replace LN2 hosing to copper(4 days) Replace HV breakers in 5 of the old linac stations (Rack A5) NTF will want to run Will be down completely for 3 weeks in July.(no NTF running

Major Booster Jobs Corrector Installation 10 weeks (S) Start & Finish Short Straight installation Finish long straights (even locations) GMPS – transformers and switchgear Install L12 kickers (S) L14 manifold Switch MI8 line Booster components on to Booster LCW. Repair candy cane/choke leaks/old tubing Septa MP02 and MP03 strip line and flags

Other Booster jobs Booster 400MeV vacuum repairs(2 days Move BV809 valve ds of B:V809 (depends on MI8 vac) From instrumentation rebuild several multi wires in 8gev line (will the parts get here in time?) Replace B:Q803 power supply Replace B:CPSDMP and B:OCT power supplies Connect B:HTMH22 near 400MeV line Install GMPS hipot switches Replace tunnel sump for old 8 GeV line Replace old isolation valves with ball valves Install new East Gallery LCW return line Install LCW Return lines to CUB Laser Profile Monitor installation (maybe). FESS relamping tunnel lights

Mi 2 nova buildings 10 weeks for Mi 14&40 1 week survey(S) Install 7 kickers in mi days (s) may not be be ready for start of shutdown Install beam valve mi52 & electron cloud and micro wave absorbers (12 days) Mi water change 720 hoses 50 days Clean last of 4 heat exchangers 12 days) Relamp lights Pipe fitters in Mi40 flournate new line 3 weeks will be done(contractors) 2 New shielding mask at 307 (3 days)

Tevatron Warm A-3, D-3, D-1, E-1, F-1, to repair cold leaks. Only 4 house will be warmed up still deciding which 1 of the 5 won’t be done. Leak test to determine leak area F-2, E-2, B-1, A-1, A-4. 1 Week Start installing new turbo’s with new pumps 43 days Misc. gauges 12 days Fix phasing to 480 volts around tev ring. 20 days Install Vertical Crystal Collimator. 9 days Regenerate NEG strips at E-0 &D0. 7 days Tev water clean 6 heat exchanger 12 days test emergency lights and bulb replacements

As found B0 and D0 low beta quads.If movment needed more discussion will occur. Roll measurements of all quads and dipoles (operator help?) no survey needed. Un roll 60 quads and dipoles around the ring(s) 4 a day (Won’t warm up)15 days Change B0 low beta HLS sensors to capactive read out types Maintenance on D0 low beta HLS sensors add water replace any bad sensors Maintenance on Tev quad HLS sensors add water replace any bad sensors Replace 4 bad dipole stands and 4 bad quad stands (s) Fix bad vacuum guages as possible Fix bad oxygen sensors Conning towers (Probably Not) Maintance 24 days

Pbar Replace Inject bend (IB7)s in xport 4 days Install momentum collimator 2 days (S) Two 4-8 ghz kicker tank at(40-50 sector)move it towards pit,7-8 feetaccumulator needs bake) aprox 3 weeks.(s) add door at pre target 2 days h20 leak manifold hv100 string replace manifolds tech divisions 4 magets who will install 16 days (4 days per magnet) target station( sem) install? Target group s Pre shutrdown a60 straight ice ball. Install vacuum valve and remove cap off. For all hydrogen experiment e862 Maintance 10 days

Recycler TSP maintance etc 8 days Pelatron maintenance big list 25 days Changing kicker at RR weeks Flushing and replace glycol in mi31 glycol skid Move magnets( some survey requests)(s) Numi Remove all dipole covered in steel refurbish manifolds with peek put back steel, this job chokes tunnel creates potential road bock to other MI access. (S) 3 people speciality needed Replace hadron monitor in minos obsorber hall 15 days (high radiation) Fix water leak in horn 1 and 2. (S) Target replacement(3-4 weeks) (s) safety, mechanical General maintance 10 weeks+ Sy120 Change 2 epb dipoles in xfer hall in extraction line(3 days )(s)

Summary: 2 separate master sub outages(6/22 & 7/27) 2 separate Kautz rd sub outages. (7/27&8/24?)

Fess Other stuff Lots of feeder maintenance means more power outages. Fix oil leak on AP50 and AP50-22 (not house pwr)

Master sub off 4 weeks Replace 1 SF6 switch on L11120 (Jumper out for one winter) Fix Transformer 84 tap changer at master sub. T83 tap changer maintenance. T83 replace lightning arrestor. Ocb test master sub Batavia needs to add 36 large grounding straps on all master sub. power poles. Connect 36 grounding straps for static line. Batavia needs to paint all 18 power poles from master sub (Batavia) 4 weeks (scarry)

Kautz off (4 weeks) Install 3 SF6 switches for kautz rd substation( all 3 switches will be jumpered out for one winter) Add dampers and repair static ground lines 345 kv and relay testing Krs main breaker maintance CB119 breaker maintenance(345 kv breaker) SF6(10 year maintance) All 13.8 kautz breaker maintance. Battery system maintance

Engineering projects Feeders 96/97 extended from Mi8 to Mi10 part of MuNu project(pulsed PwR) Feeders 82/85 at Mi60 add new switch and transformer and Pad for Mi RF Fcc electrical upgrade Sy service building transformer off for 1 week; (building on generator)Purpose to run power to FCC to power a new transformer. (Means we are adding a FCC transformer on to feeder 43 (SY))

Fess water Need to install 2 new 95Lcw pumps(these are big pumps) one already leaks like a sieve Both are older than most parts of the lab. Need 2 days with CUB off( will schedule on weekend) for maintance. 55Deg LCW water off 2 weeks to install VSD & and work on Chiller.
