Using a diode-capacitor voltage multiplier would require
6x or so to get near 8okV and the available current would
be less than 1mA.
70-80kv at .3ma will do a decent job too.
High voltage at medium power levels (like 500W) is still
an "interesting" implementation.
or 4.2kw : )
Grant, I deduce that the exposures were about 2 minutes--
is that right? If so, it would be hard to reduce the power
level by increasing exposure time, because of CCD noise.
The exposure of each line was 30ms. I was only operating the tube at
1/4 power. If I cranked it up to 80kv 20ma I could have done the shot
much faster.
BTW, is this a direct line-scan CCD image, or is it a full-
area image? (I assume no "lenses" are involved.)
Its a line.
If you ever tried something like this your best bet is to submerge the
tube, transformer, and doublers in oil and seal/vacuum all the air from
the bundle. Otherwise you're going to have arcing all over the place.
There are places that will sell you just a tube. A little tiny one the
size of a D cell battery that work pretty good. (30-40w)
