Accelerator update, Sept. 3, 2013

Linac and Booster
AD personnel operated the Linac and Booster accelerators and conducted machine studies.

Main Injector/NuMI
Workers finished vacuum work in the 307-309 sections of the Main Injector. Beam was back in the Main Injector by Wednesday evening, Aug. 28. Main Injector beam studies resumed. Operators sent proton beam down the NuMI beamline for horn scans. Over the weekend, workers installed the carbon target in the NuMI target hall to prepare for the production of neutrinos. First post-shutdown neutrino beam to Minnesota is expected to be delivered this week.

Fixed-target area
AD personnel plan to send beam to the Switchyard absorber this week. A magnet in Enclosure C (H201-10) was replaced and aligned, and final connections are under way. Work on the Neutrino Muon beamline berm pipe, which will deliver beam from the Switchyard to the SeaQuest experiment, continues.

Power outage on Sept. 1
A feeder fault on feeder 43 at 10 a.m. on Sunday, Sept. 1, caused a power outage on the Fermilab site and glitched many other systems. Operators recovered the accelerator complex by 3 p.m. FESS repaired the fault, and feeder 43 was re-energized at 5 p.m. Areas including FCC were returned to conventional power.
