Richard,
I to have some reservations about using a lucite ball but
at these voltage levels everything conducts, or holds a charge, or
bleeds energy at some rate. Its to bad you live in Virginia, we have
at Crane a large Vacumm chamber and plenty of Thermal imaging units.
I'm sure that a few of our engineers would be curious enough
to launch a short "Engineering investigation" into the phenomena of
electrical discharge heating of atmospheric gases.
Please keep me posted I'm very interested.
Note: It would be nice once again if we could get some e-field
models for some of this work. Does anybody have a general
purpose e-field modeler that does more than a torus.
