Hello everybody.

The search for a 20 kV plug/socket connector ended with the Caton type, the
best
and cheapest choice (about $80 per plug/socket pair).

Still, we decided to make our own connectors out of Teflon. With a lathe,
we got
a very professional looking connector, pretty small and cheap, standing up
to 30
kV DC (before corona starts).

After mounting six of them in the power supply rack and making new cables, we
tested again today the supply connected to my old TC: voltage was set to 10 kV
and repetition rate to about 300 Hz.

I got a single fat streamer going from the toroid to a grounded point over 50"
far: my TC has never reached that far before!

After a couple of seconds (the same streamer was still on) there was a breakout
on the secondary of one of my power supply HV transformers: I switched all off.
The secondary winding (of my transformer!) was having a turn-to-turn discharge,
carbonizing a small area. The power supply rack have been left in my car for
half a day (temperature about  - 3 C) and then brought into the lab. Moisture
probably got condensed in-between the mylar/copper layers of the winding (!!!).

We'll make an autopsy of the winding and probably will seal the new one in
epoxy
(under vacuum).

We were so near this time...

Regards
