Comparing 20 kV vs 40 kV feedthroughs

3. Solidworks model

4. Solidworks model
This 40 kV feedthrough prevents us from having to change the pipe to the 1.5” OD that interferes with the coils. The Kovar recess measurements where “eyeballed”. The HV spring guide connector requires mods.
0.06” gap
Between 1” OD and 0.75 OD insulator

5. Solidworks model
The tip rounded could be removed to improve contact with feedthrough Kovar recess.

6. Solidworks model
Modeled in Solidworks
40 KV Single Pin CF

7. Solidworks model Modeled in Solidworks
Based on Electrical feedthrough CAD
