Friday August 6
The day shift began with store #3711 being terminated at 9:00 AM, the Tevatron (Tev) was then prepared for access to look at D1 vacuum problems. Beam continues to Switchyard 120 and MiniBoone.
At 10:12 AM problems continue with the Debuncher kicker (D:EKIK), techs have decided to change it out.
At 1:00 PM Cryo techs completed the change out of a kautzky valve in the Tev. Cool down has started.
Debuncher kicker work was completed by 3:00 PM, we then returned to Anti Proton Source (Pbar) stacking.
The Tev was back on by 6:30 PM. Studies in the Tev have begun.
Tev shot setup began at 11:33 PM.
Saturday August 7
The Midnight shift began with the Tev in shot setup, and with beam to MiniBoone and Mtest.
At 3:20 AM Main Injector (MI) RF8 supply tripped off and continued to trip when reset.
The supply was removed from the loop.
Store #3715 was colliding by 3:27 AM with an initial average luminosity of 59.77 E30.
At 3:31 AM Pbar returns to stacking.
At 11:31 PM we began experiencing controls problem in switchyard, the problem was traced to a bad crate power supply, supply was replaced.
Sunday August 8
The Midnight shift began with store #3715 colliding, stacking, and with beam to MiniBoone and switchyard.
At 6:54 AM there was a vacuum burst in the Booster, when vacuum remained bad experts were called in to investigate.
At 10:46 AM an access into Booster revealed a leaking interface.
Beam returned to Booster at 4:00 PM, after repair and vacuum pump down was complete.
Store #3715 was terminated at 5:58 PM.
Tevatron shot setup began at 6:13 PM, with store #3717 colliding at 8:47 PM with an initial average luminosity of 76.92 E30
Pbar stacking and beam to MCenter and MTest has resumed.
Monday August 9
The Midnight shift began with store #3717 colliding, stacking, and with beam to MiniBoone, and switchyard 120.
At 1:13 AM we began shot setup to the Recycler Ring, this was completed by 1:35 AM.
Stacking has resumed.
At 4:06 AM, Booster was running with 2 RF (BRF4 and BRF5) stations down.
Continue Pbar stacking, with some Pbar studies this evening. Keep the current Tev store until tomorrow morning.
