Ya, that’s what I thought/recalled.

So here’s some of the relevant FF hypothesis re the major heat generation cycle, from the patent:

The higher atomic charge, Z, of B11 greatly increases the x-ray emission rate, which is proportional to Z.sup.2 making it difficult to achieve ignition, e.g., the point at which the thermonuclear power exceeds the x-ray emission. The present invention overcomes these difficulties using a detailed quantitative theory of the plasma focus, described below, and the high magnetic field effect (HMFE). This effect, first pointed out by McNally, involves the reduction of energy transfer from the ions to the electrons in the presence of a strong magnetic field. This in turn reduces the electron temperature and thus the bremsstrahlung emission.

The implication IMO is that almost all of the filament energy is magnetically controlled throughout, and little inductive heating occurs in the axial and sheath phases. Or am I over-interpreting?
