Jason,

Liquid nitrogen (N) boils at -195,8 degrees C, and it melts on -209,86
degrees. It is not the same thing which oxide you are trying to use; N2O,NO,
N2O3, NO2 and N2O5.
Liquid helium (He) boils at -268,934 degrees C, and melts at -272,2 degrees,
which is almost Absolut Zero. This is common gas used for
aircrafts(zeppelins), for preparing the artificial air which is used by
scuba divers(Brian will recognize this...), becouse helium melts in the
human blood in much lower % then the nitrogen from air(which is no matter
for us right now). So, it can be found on, let`s say, "market". It is used
in hospitals (and fortunate for me, my brother works in one...).
Off course, you can use one more gas-oxigen(O) It boils at -182,962, and
melts at -218,4 degrees C.
Helium and oxigen are not that danger which is very important for us. And
those gases also vaporize very fast when open the thermo tank, so the spark
gap should be closed in one. It needs very low voltage to break the spark
gap electrodes as my experimentation tells. It doesn`t supercool the
plasma-you can hardly expected to achieve absolut zero resistance(that`s
impossible-well, almost), but you can make your coil works more efficiently
then ever(however this is something which is not experimented yet)...

Regards,
Nele!
