Hi Terry:

I just ran across a paper from Sandia National Labs that compares triggered
gas and vacuum spark gaps with solid state devices, and thought it may be
interesting relative to your solid state gap work::

A COMPARISON OF HIGH-VOLTAGE
SWITCHES

Abstract
This report summarizes our experience in testing high-voltage switches that
must have
fast turn-on, low inductance, and low resistance. Our work was directed at
fuze
applications, but the information is relevant to any capacitor-discharge
circuit where a
high peak current and a rapid rate of increasing current (large dI/dt) are
of paramount
importance. This report describes our test techniques and discusses the
strengths and
weaknesses of three switch technologies: gas, vacuum, and semiconductors.

Hi All,

I have been thinking about making a solid state disruptive coil out of a GM
HEI ignition coil with the iron core removed (so it runs as a "true" Tesla
coil).  If anyone is interested, I posted some schematic JPG and PDF data
sheets at:
