Wednesday February 1

The day shift began with day two of a seven-day shutdown of the accelerator complex to replace a Main Injector (MI) quadrupole magnet (Q403).

During the day shift, a Booster person reported that the East Gallery cable pull began at 8:35 AM. A Controls person began working on six front ends (FE) at 8:50 AM. Control personnel began replacing the Time Line Generator (TLG) hardware at 8:52 AM and completed the job at 9:22 AM; testing would be ongoing. At 10:10 AM, a Proton Source person turned off the 400 MeV area quadrupole magnet power supplies for 30 minutes. Operations reported at 11:58 AM that Linac was back on TCLK timing. Control personnel reported at 12:15 PM that the TLG was considered operational. Interlock personnel began conducting safety system tests at Meson enclosures M02, M03/4, and M05 at 1:19 PM. A Linac technician reported at 3:14 PM that he had completed his repair of a RF station (LRF1). A MI person reported at 3:25 PM that the MI work on the quadrupole magnet (Q403) replacement was progressing well; the welding was done and the vacuum pumpdown had started.

During the evening shift, LRF1 tripped off at 4:25 PM; it reset. A Linac person began a study at 5:30 PM.

The midnight shift began with day three of the seven-day accelerator complex shutdown.

During the midnight shift, at 12:23 AM, Operators found the Linac Klystron cooling water skid #1 was off; they turned on skid #2 in its place. At 5:13 AM, KRF1 tripped off; it reset. At 5:40 AM, KRF3 tripped off; it reset. At 7 AM, Neutron Therapy Facility (NTF) personnel began preparing to treat one patient later in the morning.

During the day shift, Operators reported at 8:15 AM that the scheduled two-hour MI-8 power outage had begun. Operators reported at 8:30 AM that the scheduled four-hour MI-12 power outage had begun. A Linac person began work on LRF5 at 10:35 AM. A Water Group person began work on the Booster glycol skid at 10:46 AM. A Linac person began work on the Buncher at 1:03 PM. Booster personnel began valving in magnets at 1:46 PM. FESS personnel reported at 1:47 PM that they were cleaning strainer baskets at Tevatron sectors E4, F1, F2, and F3; they had the job completed by 2:55 PM. Operators reported that the multiwires at MI-8 were off due to a bad power supply; this will be repaired on Friday. FESS personnel reported at 3:54 PM that they had repaired the air handler in the MI-60 North Power Supply room. Operators reported at the end of shift that the MI abort Lambertson bakeout had begun.

During the evening shift, FESS personnel reported at 4:36 PM that they completed cleaning the MI strainers. Operators completed a search and secure of the Booster at 6:45 PM. A Booster person began preparing for a hipot of Booster at 10:36 PM. Operators reported having all of the Booster power supplies on by 11:17 PM. Operations reported that the hipot was fine.

Friday February 3

The midnight shift began with day four of the seven-day accelerator complex shutdown.

During the midnight shift, at 12:02 AM, a Booster vacuum pump (B:IPRF22) tripped off; it reset. At 12:17 AM, LRF2 tripped off; it reset. At 1:55 AM, KRF1 tripped off; it reset. Operations prepared Booster for access at 6:16 PM. A Linac technician began working on LRF5 at 6:54 AM. At 7 AM, NTF personnel began preparing to treat two patients during the morning. Operations turned on the Muon Rings at 7:34 AM for Accumulator power supply evaluation studies.
