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 (vent gun to remove electrode ~ August 10)
• 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 (11801C or CSA803? or something newer?)
• 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

OSPs:

• Tile removal
• Commissioning plan/MeV OSP
