It's not a degre, man. It just is

BTW IIR Darpa did succeed with something simlar to produce neutron (or X-rays?) with static electricity on a tape to produce another through-the-wall sensor.
Incidently Muons are a key component of "Muon catalysed cold fusion." So called because it has been demonstrated IIRC at liquid Nitrogen temperatures.
Yes, MCCF is a real thing. It has been repeatably demonstrated. But no one has ever focussed on creating an optimised Muon generation system. Since the raw component generation efficiency is so poor the overall system efficiency is abysmal. OTOH if that were to change......
