April 21, 2022 - HV chamber layout for installation in CEBAF

Agenda

Critical path action items

1. Anode flange designed based on Injector Phase 1 but with two HV ports
   • Need to order:
     • 2 two zero length reducer 10" to 4-1/2" flanges
     • 4 weldable 1-1/3" non-rotatable tapped flanges, or already welded to tube. Shaun?
     • 4 10 kV SHV feedthroughs. (Marcy, do we have these?, how many?)
     • Ceramic beads
     • Carlos to look for alternative to Cu wire with lower coefficient of expansion
2. Screen Design
   • Marcy dimension requests media:screens18gun.pptx
3. Define layout for installation in CEBAF injector
   • The plan is to focus on layout for installing in CEBAF using DS anode flange design from Injector Phase 1 (drawing ending in 0101).
   • It is critical to define this flange by the end of April so that it can be fabricated, and vacuum degassed.
