Still I believe FF units could be made much cheaper if their capacity factor would be reduced to about 5 kw, by reducing the frequency and getting rid of most cooling, shielding…
Reduced shielding? Even if you reduce the frequency of the pulses the amount of prompt radiation from each pulse will stay the same and thus the required shielding will also be the same.
As for your basic concept… eventually you’ll get to the point where smaller doesn’t give you a cheaper power source… but where that point will turn out to be is an interesting question…
