Accelerator Update for September 11, 2006 - September 13, 2006

Monday September 11

The day shift began with Operations monitoring store 4949 and a Recycler stash, with the Collider Detector at Fermilab (CDF) and D-Zero (D0) using the colliding beam, with the Antiproton Source (Pbar) stacking, with the Linac, Booster, Main Injector (MI), and Recycler operating normally, and with MiniBooNE taking beam.

Operations established beam to the Meson MTest experiment at 8:54 AM.

At 8:54 AM, a Recycler corrector power supply tripped off, which caused the loss of 220E10 antiprotons.

Recycler experts replaced the corrector chassis. Pbar began antiproton transfers to the Recycler at 2:03 PM.

Operations established beam to NuMI at 3:40 PM.

MTest beam was disabled for the night at 6:01 PM.

Tuesday September 12

The midnight shift began with Operations monitoring store 4949 and the stash, with Pbar stacking, and with NuMI and MiniBooNE taking beam.

Operations terminated store 4949 at 12:27 AM.

Operations put the Tevatron (TeV) into shot setup at 12:49 AM.

Operations established store 4950 at 2:58 AM with an average initial luminosity of 97.4E30.

Operations established MTest beam at 6:54 AM.

At 1:44 PM the TeV B48 separator sparked causing a reduction in the luminosity.

MTest turned off for the night at 6:04 PM.

Wednesday September 13

The midnight shift began with Operations monitoring store 4950 and the stash, with Pbar stacking, and with NuMI and MiniBooNE taking beam.

Operations terminated store 4950 at 7:07 AM. Experts began investigating the TeV E48 kicker problems.

The Plans for Wednesday

The plans for today are to establish the next store around noon, depending on the E48 kicker work. After the store is colliding, the Run Coordinator will allow accesses into the Linac, Booster, and MI for repairs. Other accesses may be allowed, depending on the jobs.
