Portable coils

Hi guys

One of the girls in our lab wants me to make a small tesla coil so that she
can do some spark processing of porous silicon (which enhances its photo-
luminescence properties). (Gosh - there goes another coil application).

Problem is, the coil would need to be portable. This precludes the use of an
RF ground. I was thinking that if I made a bipolar, centre driven coil, and
caused the sparks to pass between the ends of the isolated secondary, then
there should be no need for an RF ground. Hopefully if the coil was sparking
in this configuration there would be no RF interference with lab kit etc.,
provided of course that I put sufficient RF protection round the transformer.

Does this sound workable?
