Difference between revisions of "April 13, 2022 - HV chamber layout for installation in CEBAF"

Revision as of 09:35, 12 April 2022

Critical path action items

Let's make two version of anode tube:
- One version will be permanently at ground
- The second version will be electrically isolated
The anode DS flange design will be based on the flange design from Injector Phase 1 (drawing ending in 0101, see below), but with two feedthrough ports.
- Marcy, Joe mentioned installing this flange in the injector was a challenge: the ports gets in the way for assembly? How would having two ports affect this? Is there a better way to place them? See pictures below.
Verify HV chamber dimensions
- Shaun: is this needed for defining anode tube length?
- Do you have HV chamber prints from Lekser?
- Do you need S&A to measure HV chamber?
Marcy, what are your conclusions on the HV chamber vacuum?
Layout for CEBAF installation
- The plan is to focus on layout for installing in CEBAF using DS anode flange design from Injector Phase 1 (drawing ending in 0101, see below). It is critical to define this flange by the end of April so that it can be fabricated, and vacuum degassed.
- Anode flange prints and pictures
