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
   • The tubes and mini-conflate flanges for the anode and tube biasing feedthroughs are being welded, expect to be done today
2. Screen Design
   • Bubba and Carlos used Shaun's design as a baseline, but had to change shape a bit to make sure the beaded NEG wires and feedthrough are covered
   • Next, each screen section will be UHV cleaned and vacuum fired, perhaps along with the anode parts
   • Screen pictures
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".

4. Clean room in LERF Lab 3A
   • Clean room has been cleared off
   • Lights have been replaced
   • Next is to clean up the clean room and keep it clean
   • Carlos verified that there is nitrogen available in Lab 3A
5. Other items
