-Let's meet on Wednesday from 3-4pm in TL-1227 to discuss possible CEBAF injector vacuum upgrades.
+[[Ion Pump Power Supplies - February 20, 2019]] - Discuss future IP and IP PS requirements
-;Overview
-:Injector Upgrade - Gun through Quarter, maybe through FC2 gate is being rebuilt
-:Timeline/Opportunities - SAD (Aug-Oct, 2019), Upgrade (May 6, 2020 ... for 6 months)
-:Review Marcy/Daniel survey of injector IP power supplies [[media:190220_IP_Summary.xlsx]]
-;Existing Power Supplies
-:John's serial UHV work => unique design (low power 100uA, have interlock option, digital comm for readback, HV set, interlock limit?)
-:Digitel supplies work => aging, poor resolution (high power mA, many ganged pumps, analog ADC readback, interlock limit boxes?)
-;IP PS Upgrade Considerations
-:Ion pumps
-:: Provide holding voltage with nA or uA curren
-:: Provide starting current of X uA?
-:: Independence (Adjust HV set on any IP, monitor current on any IP, interlock any IP)
-:: Still require some high power supplies available for bakes, activation, readback helpful, interlock probably not necessary
-:Power supplies
-::Gamma SPC => experience in rest of machine, nA resolution, EPICSs
-::INC UHV => INC own/evolve design?, used at UITF, sub-nA resolution
