Interesting excerpt:
“The electron beam carried about 0.5 kJ of energy and the plasmoid held about 1 kJ of energy, nearly half that stored in the magnetic field of the device. So, this is evidence that a substantial part of the total energy available is being concentrated in the plasmoids and transferred to the beams.”
The electron (beta) beam is not the one to be exploited to extract energy, of course; it’s the alpha (helium) beam, which is not mentioned. I’ve been wondering how that beam is being handled in this experimental rig. It seems not to be used or measured in any way as far as I can tell.

Yes, the “missing” ion beam sticks out. I think he was thinking that we all know it’s balanced by the electron beam’s energy. The drift tube has a Rogowski coil at each end, last I heard. I doubt LPP’s ignoring that output, since it can provide electrical unity in one of Eric’s break-even scenarios.
