Those of you in the USA might be curious at what sort of $$$ it takes to
start fooling with argon.
I'm leasing (from a welding supply company) a large tank which holds 125
cu ft at STP of argon. Cost me $140 for a 15 year lease, pro-ratable,
which converts to something like $9/yr! If I get tired of doing this I
can give the tank back and get the remainder of the lease time back in
cash, etc. Thats worth $9/yr in my book...
Refills cost about $15. I haven't ever run out! You can do lots of
neat things with argon, as Mike Harrison has indicated on his page.

Don't know what would happen. Does the argon glow due to the frequency
(ie - capacitive coupling) or would it work with DC at all?
I'm might try building an argon-triggered spark gap (for a non-tesla
application-crush crush!). Two polished electrodes which are positioned
far enough away as to hold off 20kv or so. Triggering would be
accomplished by blowing a puff or argon into the gap. I'm told that
argon has a better ionization percentage than does air - it might make a
less lossy switched gap.
Comments? I've blown argon over RQ gaps attached to my coil and not
seen in change in output so maybe this won't work...
There is a surgical tool called an ABC - short for Argon Beam
Coagulator. Also called an APC - Argon Plasma Coagulator. Argon passes
over a HF/HV electrode - and emerges as a plasma. This plasma then
'scorches' tissue to suppress bleeding, etc. A nontechnical webpage is
Follow the links for electrosurgery...
