UITF Meeting - May 20, 2019

UITF to do list_for ARR

1) Binder in control room that lists qualified Operators 2) Describe training 3) Minimum staffing requirements 4) Pre-Ops checklist, RadCon checklist? 5) How to notify in broad sense whether UITF is a “gun test stand” or “accelerator”? 6) Professional way to lock out the valve to QCM, the dipole to elevated beamline 7) Modifications UOD: a) specify that for keV ops, rad survey is not required. B) Break the page for staffing table

Top of Cave1 and 2:

• Move wooden boxes somewhere • Bolt down the channel for magnet rack#3 • Crane up the magnet rack • Vacuum the top • Tell crews to take their un-used stuff way (cables and tools, etc) • Pick a time and ask Neil to reconfigure the helium vent barrier • When the helium vent barrier is removed, HDIce to reconfigure their vent pipes • Neil to add fall protection at the removable tile locations • Neil to provide support posts for horizontal lifeline • Andy to purchase more moveable yellow railings • Somebody to provide a means to leave the north side of the roof

Inside the caves, waist height

• Clean up and organize inside the caves, vacuum on order • Attach magnets, cable up, software screens • Viewers, air and video • Cup and dumps: water and current monitoring, protection diodes, screens • Lead brick around dumps • Lead brick in trenches, document and post • Move laser table to GTS • Harps, need them to work (harp screens, where are they) • SF6 resistor tank • 11 L/s ion pump added to the dead chopper chamber pump • Gun at 200kV w/o field emission • Activate a photocathode • Gabriel data • Lifetime with cesium • Lifetime with cesium and lithium • Beam through Brock cavity polarimeter • Characterize the buncher using the Brock cavity bunchlength monitor • Get another Brock bunch length cavity and install it at dump • Buy another scope and fast plugin • Ion pumps ON and attached to UHV supplies, with epics screens • Once harps are installed and Brock bunchlength cavity #2, light bake of beamline to obtain 100nA pressure? • Does anyone have a plot of ion pump response versus beam loss? • Curt Yao cavity electronics • Epics control of valves • Waiting for the “good” valve chassis that lets me segment MPS into three zones • Implement three-zone MPS with Marie Kissee • Official lock on QCM upstream valve? • Are we prepared to have epics control of QCM valves?

Elevated Beamline

• Re-arrange the components near HDIce (Phil, Marcy, Shaun, matt) • Waiting for stepper stages, machine shop apertures • Build the apertures and align them (need stepper motor controller, John help us!) • BPMs in place, connected to receivers • Pump down, leak check • FEL style viewers working, modifications necessary? Cameras, video, air pressure • Valves • Ion pumps • Decarad near the apertures • Steering magnets from LERF • Cup: water and current monitoring, protection diode, added to screens
