E gun design - XEI internal chat
Draft:
- Gunn briefly updates current status of the gun developement and test results
- Weak point is thought to be the ceramic resistance as it is hot in vacuum at high voltage
- For the first iteration, russian design seem to be good but it is too large to fit in the expansion solenoid and flange will be at high voltage
- Gerard: making the electrodes lighter will help in mounting seembly, there ideas that needs to be though through
- Also look at the integration of cooler in the ring to see if extra length of the gun will allow easier maintenance
- Adriana: take help of MME for thermal simulation, check the resistance with the literature values
- Meet again sometime in september when Jean is back
