They created APLAC didn't they? Too bad the student version is so crippled.
I could use a microwave FDTD simulator.

2ndary arc dynamics. For display coils, what is the optimum RF impulse
envelope application rate for the 10KHz to 1MHz, to optimize arc length.
What forces and fields lead to arc kinking, and how can they be directed?

So you would like to see a field solver movie of an arc forming and growing?
How about linking a field solver model of the growing arc-terminal to a
spice model of the 2ndry-terminal LC. Then account for the changing
chemistry as air burns to ozone & NO-xides.

How about a multi-dimensional parametric optimization program for spark gap,
inductor and arc. For a given power level, physical wire length and gauge,
primary capacitance, secondary terminal, and insulation system, find the
optimum inductor geometry, inductance, coupling and spark gap. Make'em work
for that sheep-skin :)
Ask the optimization question, which answer is "the longest arc for the
available parts and energy".

This is well studied. It might be more interesting to study personality
types and psychological profiles. Are coiler's simply geeks, enamoured by
the aesthestics of a well engineered energy system? Are we compensating for
inferiority, insecurity and lack of control by striving to master
mega-joules of destructive energy? Or are we just thrill-seeking pyro's in
search of a bigger bang?!?! Bwahahahahaha ;-)

They keep the plutonium too well guarded :(
