; High voltage test => evaluate onset of field emission in small HV chamber with tee electrode
: Install high voltage insulator or PIG
: Plan [[media:200817_Tee_Evaluation.pptx]]

; Gun work => replace cathode in small HV chamber with small shed and tee electrode
: Install and align new small shed (cut from large shed) SS tee w/ conductive insulator
: Replace 10" anode flange (no change to anode spider - tube - anode) with tapped flange for BPM
: Remove inline getters
: Build new 2I beam line (BPM-tube-BPM-tube/FX-bellows-BPM-valve)
: Bake

; High voltage test => evaluate on set of field emission, high voltage gas condition to 200 kV no FE

;The spreadsheet below contains procedures for the gun high voltage jobs described above and also for Wien filter HV evaluation
[[Media:High Voltage Work Gun2 & Wien filters.xlsx]]

; Gun work place holder => replace with large HV chamber, large tee w/ shed and off set biased anode
