Luc,

Good information except that paper has the name Marconi on it (Yuck..) . :)

Anyway back on topic, I've made a couple of trigatrons from scratch. If you
want to see pictures of their construction, firing circuit details, and
application check either of the following URL's

http://fp2.hughes-dot-net/brianb/pulse_discharge.htm (the trigatron is about
half way down the page)

Hi Mike

I have a paper that could interested you on my download site:

http://homepage.mac-dot-com/ludev/

When there open the folder "Tesla" and download the document
"3elec_sg.pdf" It's really interesting and I'll try to base my
future trigger gap in this concept ( the trigger electrode out of
the way of the 2 main electrodes ).  

Cheers,

Luc Benard

I'll try a flyback circuit too, because may be the RF corona from
it could be sufficient to trigger the gap ????
