PARTIALLY COMPLETED PERIODIC INSPECTION OF ACCELERATOR STAND TORQUE AND MAGNET POSITION VERIFICATION
1L04, 2L03 and 2L07 insulating vacuum
Turbo pumps in 2L03 and 2L07 stopped registering gas pulses when the SL was tripped to 4K. 2L07 cold cathode gauge may still be seeing something, purple in top pane. 2L03 gauge response remained the same across the trip. 1L04 cold cathode is still seeing pulses; its pump has never shown spikes (pink in middle panel).
status phase2 injector work Day 5
Day 5:
¼ CM utubes were pulled
removed spectrometer beamline
Greg Marble cleaned up the two warm girders on ¼ CM, removed one of the pump carts used on ¼ CM insulating vacuum space (used for 30 years!, what a pump)
RadCon cleared some debris: magnets and related things now stored in ISB cabinet, trash to dumpster, some useful beamline components delivered to TL1137 for installation on new girders
RadCon noticed activation along beamline, between ¼ CM and approximately A3 aperture. Will need more surveys performed as we continue to dismantle beamline
