RE: [TCML] Spark gaps, Solid state switches and diodes

["Gary Peterson" <g.peterson@xxxxxxxxxxxx>]

Would an adjustable hyperbaric spark gap placed in between upper end of R1
and the collector of the first IGBT provide SISG quenching?  The idea is to
have the transistors initially close the switch, as usual.  As the primary
capacitor the voltage decreased the voltage drop across the quench gap would
also decrease and the spark would extinguish itself.  The idea is to turn
the circuit controller switch off before the second primary capacitor
discharge cycle begins.  I've also seen a sulfur hexafluoride filled
adjustable spark gap, which might be used for the same purpose; that was at
Golkaland, CO.

Bart Anderson might want to investigate such a modification to his SISG
machine in preparation for his upcoming experiments.

Install a hyperbaric spark gap and you will be really amazed at the
performance increase.
