The Van de Graf was built by, well, Van de Graf in the 1930's to power the
early accelerators that the physicists (MIT?) were playing with in Boston at
the time, according to what I was told. The TC's are of uncertain parentage;
they looked kind of old and their sparks were rather unimpressive in
comparison to the BANG! that the Van de Graf produced under a full head of
steam. I was expecting some fat sparks from them and the day I was there
(mid-June '96), they only produced some fairly anaemic streamers. They
probably needed some tweaking; list members in the Boston area take notice!

The whole show impressed my kids and scared my wife to death so it was a
worthwhile thing to do. I do wish that I could set up a Faraday cage like
the one that was there.
