Mike,

Most hydrogen thyratrons can't handle the two way current
flow in a TC.  Two thyratrons would need to be used, with
suitable switching so neither sees reverse currents.  Richard
Hull once tried such a project, but just used one thyratron,
and pulsed it for only 1/2 cycle, which limited the output.
Maybe someone will try the two thyratron method.  I was
going to try it, but never got around to it.  

cheers,
John
