Proton Source, Linac and Booster
Commissioning and studies are in progress. Workers carried out maintenance in Linac and Booster on Aug. 13 and 14.
Work continues to find the cause of the vacuum problems in the 307-309 sections of the Main Injector. The goal is to achieve a high vacuum of 10-8 torr. A contaminant inside the vacuum system has led to a higher-than-normal gas load. While this is acceptable for low-intensity beams, the vacuum needs to be improved for high-intensity beam operations. Accelerator Division sent out samples of bellows and other material inside the vacuum for testing for chemical composition.
Work on the Neutrino Muon beam line, which delivers beam to the SeaQuest experiment, progresses well. New beam pipes have been installed along approximately half the length of the beam enclosure. Welding of the third set of pipes is in progress.
