#462642 — HV discharge switch

 What is the proper name for the three terminal encapsulated discharge 
device that has the HV terminal, the ground terminal and the terminal
for the injected ignition arc to force the HV terminal to arc over to 
the Ground terminal..

 The last one I saw was round transparent glass bubble with the main 
ends on it and the ignition probe off the side close to the ground end.


These units are used for very high voltage discharges using a smaller 
ignition arc as the switch.

Thanks.

There are a couple of such devices: a trigatron and a field distortion 
spark gap.

 YEs we have a winner, that is what it's called...

 We work with HV devices and looking for a practical decharge device to
bring down HV up in the ares of 40K and up, some cases could be 100KV.

 The voltage is variable so we're looking to automate the gap so we can 
adjust the break down of various set voltages so inject an ignition 
pulse to collapse the gap.
 
 We will be experimenting with inert gas, maybe SF6 will do it, we have 
plenty of that around and its heavy so it'll say in a nice holding cell.

Thanks

Triggered spark gap?

Thyratron?

No - a thyratron is a gas-filled vacuum tube.

An ignitron is a different beast, though.

Cattle prod? Electro-stim?

Definitely an Electro-Stim.  ;-)

 I'm working on a 10kV 15-ohm 200ns MOSFET
 discharge switch, 500pF discharges at 2kHz.

You might be thinking of the sprytron.
