It is a helix TWT made in Germany with no documentation and yes, adjustment difficulties are probably the reason you can even buy these things cheaply at all - but remember, for simple irradiation applications we aren't talking about getting the thing to transmit in precise ranges of a few Khz - but only to put out a few hundred watts at frequencies that can vary all over the place - or in the case of a plasma window to dump a mix of electrons and photons into an already created plasma.

But you're probably right about this not being the most promising idea in the world as I don't think microwaves are anywhere near the frequenices that are required for resonance... however, back to the subject of plasma windows, do you recall the Kapitza atmospheric pressure reactor? I can't seem to find it in my files.
