Operation Summary for March 14, 2012 - March 16, 2012
 

Wednesday March 14

The day shift began with Operations monitoring the Linac, Booster, and Main Injector (MI), and with the NuMI, MiniBooNE, and Meson FTBFT-1008 experiments taking beam. The Neutrino Area enclosures and SeaQuest were in access.

During the day shift, Operations disabled beam to T-1008 at 8:03 AM; this ended their run. An RF Engineer turned off a Tevatron low-level RF crate at 9:28 AM. At 9:34 AM, the NuMI beam permit tripped off for the first of three times in about five hours due to a power supply (V118) tripping off; everything reset. A Muon Ring person began a study at 9:58 AM. Operations received an Operational Readiness Clearance (ORC) at 10:13 AM to send beam to the “MAP” research and development project in the MTA beamline. At 10:15 AM, Operations reported receiving a Meson MS2 LCW alarm; Operators notified a Water Group person to investigate. He reported that there was leak. Operators prepared Meson enclosures M02 through to M05 for access and found a quadrupole magnet (MT4Q3) with a leak. At noon, Operations turned off the Linac beam so that Linac personnel could work on an RF station (LRF1). Booster changed out a module for BRF2 at 12:53 PM. At 12:55 PM, the H- Source high voltage tripped off; it reset. Linac resumed sending beam at 1:05 PM. MTA personnel began a study at 3:13 PM, but a timing problem held off beam until sometime around 4 PM.

During the evening shift, at 4:19 PM, Operations reported a MS2 LCW “total flow” alarm and called in a Water Group person to investigate. The Muon Ring study ended at 5:10 PM. Operations received an ORC for the Meson FTBF experiment T-1017 and at 6:39 PM began sending the experiment beam. At 6:52 PM, the NuMI beam permit tripped off when V118 tripped off; everything reset. Operation began turning on the SeaQuest beamline at 6:55 PM. The MTA study ended at 7:50 PM. Operations established beam to SeaQuest at 9:02 PM.

Thursday March 15

The midnight shift began with Operations sending beam to NuMI, MiniBooNE, SeaQuest, and T-1017.

During the midnight shift, Operators completed a 750 KeV line tune at 3:28 AM. Operators completed a Booster injection tune at 4:32 AM. At 6:56 AM, three MI kickers (I:KPS1A, B, & C) tripped off; Operations contacted a Kicker person who reported finding a failed RF amplifier. MI resumed sending beam at 7:14 AM.

During the day shift, at 8:05 AM, Neutron Therapy Facility (NTF) personnel prepared to treat one patient later in the morning. At 8:52 AM, the NuMI beam permit tripped off due to a MI incomplete RF gap, but no MI RF station had tripped off, so Operations reset the permit. Muon Ring personnel began a study at 9:13 AM. The NuMI beam permit tripped off due to V118; everything reset. At 10:16 AM, the P2 transfer line beam permit tripped off due to the Muon Ring study; it reset. The MiniBooNE beam permit tripped off due to bad beam positions at 11:19 AM; it reset.

During the evening shift, at 4:51 PM, the Muon Ring beam permit tripped off when a quadrupole magnet (M:Q109) tripped off on a high temperature indication. At 5:10 PM, Operations reported that the Muon ring LCW system had a leak; Operators accessed and found a leak on a quadrupole magnet (A3Q11). Operations called in a Water Group person who had the leak repaired by 6:53 PM. The NuMI beam permit tripped off due to E:V118 tripping off; everything reset.

Friday March 16

The midnight shift began with Operations sending beam to NuMI, MiniBooNE, SeaQuest, and T-1017.

During the midnight shift, LRF5 tripped off at 2:30 AM; it reset. LRF1 tripped off at 2:35 AM; it reset. At 4:47 AM, LRF3 tripped off; it reset.

Operations Coordinator (OpsCo) Plans for Today and the Weekend

The OpsCo agrees with the Booster and Muon Ring study plans for today and for an hour of LRF1 work and Booster phase detector work. SeaQuest continues to commission their beamline.
