To reach 2.5kA with a 450V power supply, the coil cannot exceed 180mΩ.
I removed the Polywell from the chamber to measure resistance of the coil alone.
The coil contributes 227mΩ.
Our 6cm diameter Polywell uses 11.31 meters of 18 AWG wire.
Based on wire resistance charts, 16 AWG wire would contribute 149mΩ.
One pin of small feedthrough: 33mΩ:
The bellows feedthrough has a tiny 1mΩ. I should use this for the coils (currently used for langmuire probe):
One leg of the power supply cable with connectors: 39mΩ. This can be improved with a shorter thicker cable.
I ordered 16 AWG magnet wire.
