Linac
Marx upgrade LRF5. LRF5 water leak patch. Emittance scans. NIF (NTF) timing investigation.

Booster

Successful shutdown. Established beam to booster dump by 1600 yesterday. Thanks to all involved in work. Studies on evening shift. Turned off this morning for MI-8 access. Started booster studies @ 0845.

Booster Neutrino

Reference to beam spot motion that could be related to booster high field fallout. Tunnel work today. Possible beam this evening.

BNB Experiments

Work on DAQ.

Main Injector & Recycler

Going well. MI52 roughing overnight. Plan to have beam this evening. Reboot for RR & MI LLRF systems will be necessary. RAD suvey of tunnel completed. MI-8 ion pump cabling this morning.

NuMI

MW3 FE mentioned. Horn1 hanger valved out; leak appears to be gone (mostly). Seresco repare complete. Absorber Hall & Muon alcove will need secure.

NuMI Experiments

Took advantage of shutdown for various repairs.

Muon Rings

Made access into AP0 vault; vertical motor on target ground fault. (found wire in gears). Did leak chaecking, found small leak on ion pump feed thru. (vac sealed) Leak checking contiued. May ask operations to unlock supply(s).

Muon Experiments

Trolly run Monday evening. Used DT for maintence. Vacuum pump died, had spark started access early. May start a bit later this evening. Would like to go to 16 pulse operation over the weekend.

SY120

Gate between enc B & C fixed. H201 water leak discovered. (work in progress)

SY120 Experiments

Waiting for beam.

Mechanical
MSD Machine Reports (Mechanical/Vacuum/Fluids):
Proton Source (Kubinski):

In Booster, Leak checked performed in Periods 24, 1 &2.
Repaired multiple leaks that they found on the kickers in period 2. Leaks were found and epoxy used to repair the leaks they could address. Ion pump 2.1 was reading 1.5 10-6e before the repair was made its. As of Wednesday at 0700 its reading 3.510 -6e.
Plan today: replacing the turbo pumps on the A LEBT
Fluids (Wallace):

Inspected and patch the leak on the RF 5 skid system the leak has slowed the leak down to one drip Every 90 seconds.
Replacement for bad Debuncher LCW pump underway. Installation underway.
Booster Anode East/West skids topped off with water/glycol make up.

MI/RR (Juarez):

Thanks for the report and the hard work today, Fernando. I turned on the RGA filament from home and started scanning. The vacuum on the ion gauge spiked but came back down within an hour. Attached is a scan. We’ll leave the RGA filament on and keep scanning while you make the RGA vacuum common with the MI vacuum. I’ll check on the RGA in the morning before 8:00, but after 8:00 you’ll have to contact Kyle if you need to do anything with the RGA controls.
Make sure that the ion pump power supply for IP520D was changed to a positive supply before turning it on (since it used to be a negative supply for the triode).
Replaced the SEPTA’s 300 l/s ion pumps with the 400 l/s ion pumps.
520 region kicker magnets have been removed and replaced with the beam pipe.
the 200 AMU RGA manifold is installed, under vacuum and scanning at MI52.
Everything mentioned under vacuum overnight into this morning.
Assisted EE support and MI with the In 8 GEV ion pump repair. 3 of 4 ion pump cables or cable fittings successfully replaced.
Plan today: and today we will be able to proceed with the leakage check.
Fluids (De Leon):

MI Pond Pump bypass jumpers were implemented to facilitate pond strainer cleaning. Upon completion, bypass jumpers were reset, ACNET status verified Pond Pump/LCW operation looks good.
DI bottles in MI-60 RF LCW system successfully replaced with 4 new DI bottles.

Beamlines (Vrbos):

Oil changed and filters added to pumping station 110 in enclosure C
Interlock gate between enclosure B and C was repaired
Vacuum Leak check in muon campus D30 area took place. small leak found on an ion pump. Leak repaired using vac seal as a short term fix. Leak check underway to verify.
Fluids (Rivera/Clemons):

The leaking Dipole in Enclosure B has a bad ceramic. Repairs continuing through today.
Water leak in meson MS2 system found to be an old, rusty, leaking gauge. Old Gauge was removed and a plug put in place
F sector patches were inspected and looking very good. no new leaks found
A1 Pond Pump test will be performed today to verify pond pump configuration flow through to Wilson Hall east reflecting pond.

RF
RF 'A' & 'B' phase matched amps changed (120 Hz ripple found.) DI bottles replaced @ MI-60

Controls

Reference to splitting MW3 & MI60SB FE's from same crate. MSEPTA still an issue. Work in progress.

Instrumentation

Full report to be given Friday.
