Optimal Cockcroft-Walton Paper

Hello again. I've made my triumphant return to the boards. I just thought I would share the title of this paper. I know at least two of you are working towards Cockcroft-Walton generators. You will probably want to read "Optimal Design of a Half Wave Cockcroft-Walton Voltage Multiplier With Minimum ...

One of the things I wanted to add was a simple "tank" trap on my rough pump inlet to prevent contamination in the event of an improper shutdown.
