The prototypal vacuum tube tesla coil articl in Physical Review in the
1930's described UCSF's 1Mev xray machine which used a few turns
resonated to around 7mhz and excited with several hundred kW. Was in
a vacuum and coil was pipe so inside was water cooled. End of coil
served as X-ray anode.
At some point I will put together my Tesla biblio. again since it
never went thru several months ago. It has this article and a bunch of
other interesting stuff from prof. jounals. Rob.
