UITF Meeting - January 3, 2020

media:HDIce to do list 1_3_2020.docx

Additional FSD nodes, some/all will be maskable

• Ragowski coil low current BPM, trip beam when position and current exceeds a value determined by Kevin's Labview program
• Halo counters at the dump
• Halo counters at upstream apertures
• Decarad? Will be installed but perhaps not used as FSD
• the dump magnet must be ON
• Superconducting IBC magnets must be ON, other protection required by ERR committee?
• Raster magnets must be ON
• some sort of vacuum guage at dump and near target, can be another ion pump current I guess

I&C stuff, Cable pulls:

• We need a frequency generator to drive the laser intensity modulator at 1 MHz
• We need a copy of the 1 MHz signal delivered to the lockin amplifier rack
• Aperture/stepper motor control (three of these, two near HDIce and one at Chopper)
• Two viewers behind HDIce
• New ADC card to read the SF6 pressure, per Scott Higgins’ request (the old XY566 ADC will be upgraded to a standard VMIc0979 board)
• Remote control of the pockel cell voltages, DAC wired to the EMCO HV bricks (we won’t use the fancy RTP driver that Caryn Palatchi has you building, not at UITF)
• Fibers (4?) from helicity board to the HDIce target
• Ethernet cable from halo counters to….?

RF group:

• Buncher 748.5 MHz, and then 1497 MHz
• Heaters added to buncher, cabled and fed to 120 VAC box, Hansknecht’s controller
• Get 1497 MHz buncher made, fine tuned to be resonant
• Buy 1497 MHz 400 W amp
• Yao cavity bunch length electronics, software

Phil:

• Install 6” blank gasket with 5 mm hole for conductance limitation, in case we vent something, gives us time to close valves to protect the booster
• Install manual valve on the elevated beamline, to make it easier to bake this line

Software related:

• Halo counters, need software, right?
• Some way to export Labview info to read via epics
• Raster magnets
• Stepper motor control apertures and chopper slit
• Pockel cell voltages via DAC

Computer control:

• Remote desktop to X computers inside Cave2
• Additional wall monitors?

RadCon:

• Shielding concerns, high current at dumps, proximity of HDIce electronics
