Gentlemen,
I'd like to toss out a couple of generic CF questions
to any experimentalists out there. My little cathode
glow discharge / sheath plasma reactor is set up and
empirically optimized for cathode material (nickel
foil "sword") and electrolyte (K2CO3). Been calling
it the Wisp-1. I made up a crude neutron detector
using a nalgene bottle of aqueous manganese chloride
positioned in front of my Geiger counter head. Last
week, I ran a couple of light water runs, and saw no
appreciable effects either with TCs in the bath or
anything other than a couple of slight rise periods on
the GM counter. On one run, I did add like .5% by
volume D2O, since I had a few ml I made from burning
some D2 I had.
I now have a greater quantity of heavy water (99.9%),
and could conceivably make a run using that.
Questions that arise are thus:
1. In CF technology to date, are any positive results
found using blends of heavy and light water? I'd like
to be frugal with my D2O. The FUSOR crowd seems to be
tickled with bleeding in small percents of D2 into the
Ar or He used for the plasma. Or have aqueous CF
recipes always required the straight stuff for
results?
2. Any last thoughts on a better homebrew neutron
detection scheme? Someone hinted to me recently that
old style D cell batteries with manganese sulphate in
them made a good neutron detector for use with a GM
counter.
All notions appreciated!
Best,
NR
