Updates

1. Anode flange designed based on Injector Phase 1 but with two HV ports
   • The used zero length reducer 10" to 4-1/2" flanges from the GTS that looks it has a been baked many times has been machined and is ready for welding the two tubes for the mini-CF HV feedthroughs
2. Screen Design
   • Bubba made screen sections based on Shaun's drawings from thin and thick wire mesh
   • Marcy and Carlos looked at the screen sections fit inside the HV chamber, Carlos to talk to Bubba for making new screen sections. Goal is to finish this job by the end of this week.
   • Standoffs with holes, screws and washers have been cleaned and are being used for thee screen fit up.
   • Once the screen is finalized, all pieces must be UHV cleaned and vacuum fired.
3. Define layout for installation in CEBAF injector
   • Any updates from Shaun?
   • Carlos measured the CEBAF and UITF 14" HV chambers lengths, flange to flange: both measured 18.9". Drawing shows 18.88" ( Media:HV chamber gun 14" diameter drawing.pdf). The 18" HV chamber measured 19.6" flange to flange, Lesker drawing shows 19.66" (media:LeskerPrint.pdf). Shaun to verify with S&A numbers and his model, but that means the 18" HV chamber is longer than the 14" HV chamber by 0.78".
