Accelerator update, Oct. 21

Proton Source
AD personnel performed maintenance and tuning studies as needed.

Main Injector/NuMI
Between Oct. 14 and 21, the Main Injector provided 121 hours of proton beam to the NuMI target for the production of neutrinos for MINERvA, MINOS and NOvA. The machine delivered an integrated intensity of 5.01 x 1018 protons on target.

AD personnel repaired a vacuum leak in MI-604 and continued troubleshooting the MI-52B Septa system, along with other maintenance work.

On Oct. 18, AD increased the rate at which a neutrino beam pulse is sent to Minnesota from once every 1.73 seconds to once every 1.67 seconds. Before the shutdown, the repetition rate was 2.067 seconds.

AD personnel, with assistance from the alignment group, continued work on the Recycler aperture. They identified an aperture restriction at a welded area in the beam pipe, and it will be addressed during the next access.

AD personnel worked on extraction and beamline tuning.

Fixed-target area: Test Beam Facility
AD personnel worked on tuning beam for the Meson Test experiments in the Fermilab Test Beam Facility. Experiment T-1036 was installed in M03.

Fixed-target area: SeaQuest
Experts installed magnets and connected instrumentation in preparation for the startup of the SeaQuest experiment. They also began pumping down the berm pipe.
