RE: [TCML] here's an ebay item that may have some interest - Xenonflash with thyratron/timebase

Hi Bill,

Do you think the Xeon will have enough Ultraviolet ionizing frequency and
intensity to trigger a 5KV, 3KJ discharge gap?.. maybe the trigger
transformer output... I am interested in doing that. The goal is to scale up
to my 50KV caps; either of which demands a lot of respect! I had some nice
2.5" gaps machined out of brass dowels - an external trigger would be great.
I have come up with a 555 count down circuit and a CDI but haven't tried it
yet.

The other option is to set the gap at the breakdown voltage and control
charging remotely. Perhaps gap breakdown is close enough to what we do that
Chip will post this for comments :-) I know some pull a string from a
distance closing the gap mechanically to accomplish this.

Thanks Much,
Jim Mora

I scrapped an oscillograph a long time ago, I'm trying to make more room in 
my garage, so some pieces gotta go - this thing may have some interest to 
the folks here - it drives a xenon flash tube via a 2D21 thyratron, it was 
working when I pulled it out of the oscillograph, and it might have some use

in setting up a spark gap or something - or it could be just for parts?

anyway, here is the ebay listing should you see a way to make use of it.
