New action items
- Electrode/insulator design/fabrication
- Danny/Gabriel/Carlos will iterate on final design : minimize gap over triple point, optimize ceramic/metal gap curvature
- Build electrode/shed from one piece of material 8" cube, not enough Nb, go w/ SS
- Matt will check on 316LN vacuum melt, but let's still check what shop used for 350kV ball electrodes, maybe save time and money
- Plan is to vacuum fire 900C, barrel polish before attaching to ceramic
- Reuse springs/rollers/cage, but new rear support ring optimized for electrode
- Collect as-found on white insulator assembly and black insulator
- Finalize design by next week, get to shop
- Vacuum chamber/considerations
- Plan A - Use as-is, but identify/repair short of NEG isolation, retain leak valve but add right angle for isolation
- Do we forego NEG isolation and remove unnecessary ceramic plates (fallen to bottom of chamber)
- Plan B - Rotate NEG's => remove NEG's, weld support rods, NEG coat chamber, return X number of NEGs, new ground screen, retain leak valve w/ right angle valve
- Gun2 NEG Tube
- As-found of existing Gun2 NEG
- Find/leak check cans
- Give Danny sketch of sequence for new tube w/ BPM's + magnets, eliminate/shorten downstream bellows
- All assembled FH solenoids spoken for; take from Gun3, maybe spare parts, or fabricate new coils
- Gun3
- Retain downstream chamber w/ extractor, RGA, GP-100 w/o NF3/Cs
- Remove gun table and HV section
- As-found of existing Gun3
- Gun3 Software
Hello Joe, I'm coordinating with Scott to rewrite the gun switch software for one gun operations. Looks like we are going to gut most of additional gun code simplifying the solution we currently have. For the front end, I wanted to meet with you to get an idea of what things you're looking for on the screen. I'll be on shift next week Monday - Wednesday from 2-10 to support the injector work. Hopefully we can talk then. Best Kyle
