Details Solidworks model CST simulations |E| Ey Ez Comparing 20 kV vs 40 kV feedthroughs

Solidworks model

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

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