Accelerator Update for January 18, 2006 - January 20, 2006

Wednesday January 18

The day shift began with Tevatron (Tev) A4 vacuum repair in progress, the Recycler Ring (RR) stash at 214.8 E10, Antiproton source (Pbar) conducting studies, and with MiniBooNE and NuMI taking beam.

At 2:08 PM, Meson Test (MTest) requested beam and received it.

At 3:17 PM, Meson Center (MIPP) completed repair on their analyzing magnet (F:MC7AN1), they are taking beam in the data taking mode.

MTest turned off for the day at 5:14 PM.

Pbar studies are finished at 9:20 PM, Pbar has returned to stacking.

MiniBooNE experienced some downtime due to power supply problems with E:H865 and E:H866.

Thursday January 19

The midnight shift began with Tevatron (Tev) A4 vacuum repair in progress, the Recycler Ring (RR) stash at 190.8 E10, Antiproton source (Pbar) stack at 55.5 E10, and with MiniBooNE, NuMI and MIPP taking beam.

Operations put the Recycler into shot setup at 6:09 AM to stash antiprotons.

Pbar returns to stacking at 7:12 AM, beam also returns to MCenter.

PBar went into access at 7:18 AM.

At 9:10 AM MiniBooNE began running in the anti-neutrino mode.

Main Injector (MI) studies begin at 9:16 AM.

From 1:05 PM to 3:35 PM NuMI experienced horn power supply trips due to the horn stripline. Problems were resolved and NuMI is once again taking beam.

Pbar access is completed at 2:49 PM.

Pbar studies begin at 4:01 PM.

Friday January 20

The midnight shift began with Tevatron (Tev) A4 vacuum repair in progress, the Recycler Ring (RR) stash gone due to studies, (Pbar) conducting studies, and with MiniBooNE, NuMI and MIPP taking beam.

PBar studies are finished at 1:06 AM.

MI/RR went into access at 5:50 AM to replace a DCCT for the recycler stash readback.

Main Injector beam returns at 7:36 AM.

Beam returns to NuMI, MiniBooNE and MIPP at 7:43 AM.

The Plan for Friday and the Weekend

Pbar and recycler studies, run beam to NuMI, MiniBooNE and MIPP. The Tevatron could be cold as early as Friday evening.
