Interesting.  U.S. patent 5,079,482 does appear to include some a novel
expression for the mutual inductance of a sprial strip, as well as the
self-inductance of the secondary spiral winding.  These expressions would
facilitate the implimentation of the sprial strip design without having
to resorting to external tuning inductors.

Patent 5,079,482 cites US patent 4,931,700, also by the inventor Jay L.
Reed, which provides details of the electron beam gun.  The electron gun
generates an intense relativistic electron beam that does not require an
evacuated enevelope.

I wonder who this work was done for, and if these devices were ever built.
