My limited knowledge tells me this means it "stays switched-on" once fired, 
until the forward current source disappears that is.

How would this work with our RF cap oscillations ?

Would the zero current crossing following the "bang" result in the "switch" 
going into the off state ??

Could you run a charging DC supply into it, then use a triggered pulse 
circuit for firing frequency ???

Any more thoughts from the EE types ........ when I say limited knowledge, 
I ain't kidding :-(
