Sing Lee’s equivalent circuit diagram and labels rely heavily on the word ‘fraction’. The backplate’s inductance and current fractions are significant contributors to the machine’s performance or lack thereof. Have any of his students reported any experiments to reduce backplate inductance? I remember reading one that proved a short metal plate was a lower inductance capacitor conductor than the standard issue wire, for instance.
I’ve sketched cap bank geometries a few times since my last post. Danged frustrating things to put close together! It’s starting to look like a 3 by 3 or 3 by 4 array might be the lowest impedance HV system…
