CEBAF Wien Filter Upgrade Iterations

200kV Wien filter - V3 - Third iteration modeled in CST by Gabriel with improved 40 kV feedthroughs has demonstrated (2019) 20kV per plate at UITF on a test stand but test still undergoing. Intended as a testbed for 20kV switch chassis test in preparation for implementation at CEBAF.

200kV Wien filter - V2 - Second iteration built using 20kV feedthroughs and HV tested in UITF beamline 2018 to ~12 kV limited by large vacuum excursions

200kV Wien filter - V1 - First iteration to modify CEBAF Wien filter for 200kV operation, fabricated per Jay's proposal, and installed at UITF 2017
