 Were you generating a large amount of X-Rays with an evacuated tube
 setup of that sort?    Stephen Sanders

Stephen (and all):

No.  Perhaps I should have mentioned the gap was operated at "low
pressure,"
i.e., down to approx. 100-125 mm Hg (torr) and is not much of a vacuum. 
This
pressure is well above the threshold for x-ray generation and the AC
potential used in one case was approx. 2.5KV.  In the manufactured RADAR
spark gap tubes, the fill gas is hydrogen and argon at pressures in the
10-20
torr range (approx.).  X-ray generation of any significance occurs
(initially)  in the millitorr range at much higher potentials.
