The above quote seems to indicate the effect being sought is NMR related.
It is spin related. It seeks to reverse the spins and destabilize the nuclei of these elements.
I always knew that the decay of some nuclei could be influenced by external factor, such as ionization, e,g, see the spectacular example of
187Rhenium and
GSI anomaly but it wasn't until I read
this patent which made me realize that certain RF absorption by the nuclei, can destabilize them, too. The result of this destabilization is the ejection of fast electrons (fast as in: 0.9c - not to be conflated with slow electrons of regular conduction).
However, in a previous post you stated:
"A stream of fast electrons starts circulating in the ring/rod. This has the effect of producing a strong current pulse..."
Is the effect being sought moreso related to NMR or some action involving free electrons?
It is a synergy of four mechanisms:
1) the destabilization of nuclei by specific RF absorbtion
2) the directionalized emission of fast electrons (not slow electrons of regular conduction)
3) the confinement/bending of the paths of the above by the static B (as in a cyclotron)
4) electron multiplication by secondary emission
Normally, the fast electrons are emitted in random directions, however the spin axis alignment caused by the magnetic field, directionalizes this emission.
In case of this device, it is a circular polarization of these directions.
How did you arrive at the the requirement for "B > 70500 Gauss / mm of OD" ?
From the Lorentz deflection radius of fast electrons (as in a cyclotron), with the assumption of their speed being 0.9c, according to:
That the Lorentz deflection of moving charged particles also applies to the trajectories of fast particles inside solid matter, is exemplified by the enhancement of PET imaging resolution in presence of constant magnetic fields.
The photo above also illustrates that the fast charged particles inside matter, survive for several millimeters between collisions, which is a huge distance on the atomic scale.
ICRU Report #37 has more data about the mean free path of fast electrons inside metals.
