Eric mentions in the patent that the preferred pulse freq is ~1 khz to keep the fuel ionized.
This changes some assumptions, and the numbers around them. If we assume therefore that a 5 MW generator is pulsing at 1kHz instead of like 330 Hz, then this triples the heat rejection requirements.
However, I read this spring that the plasmoid size is turning out to be smaller than expected — at least in deuterium. if that turns out to be true for boron also, then it would tend to reduce the yield per shot. That isn’t a disaster, but it places tighter constraints on power conversion efficiency, throughout the system.
I think it’s time to get intimate with the properties of the exit beam, and work out how to capture it. I’m assuming it will look like this…
