Erik and Jim,
It seems you missed the plasma globe discussion. A few weeks ago we
talked about it. The following conclusions were approached:
1. Globes require either rarified atmosphere (air) or any noble gas or
combination thereof. i.e Helium, Argon, Krypton, Xenon. Different
combinations
2. Carbon Dioxide seems to work too (color is white)
3. Safety Tip: Do not use Propane or Hydrogen
4. The globes need to be evacuated to about 1-2 torr. However the rumour
persists that commercial globes (eye of the storm) are at low vacuum and
a secret mixture of noble gases allows this. Common sense seems to
discredit this: the gases do not combine covalently or electrovalently so
the individual properties should be retained. I guess we'll have to wait
until someone who worked for 'eye of the storm' comes fourth.
5. The glass should be of sufficient thickness to insure no implosions. I
wonder if there is a formula for a sphere (vacuum vs wall thickness). But
I suppose it would depend on glass type.
6. Display is affected by power supply frequency, voltage, wavefourme and
duty cycle. It is also affected by gas type/mixture and vacuum strength
7. There is a 'Plasma God' out there somewhere named Bill Parker who has
all the answers.
I am currently experimenting with a 14" globe.I am encasing my center
electrode in glass to try to achieve 'string' plasma. I use a
Sargent-Welch oil filled vacuum pump with a gage from Edmund Scientific
and plenty of vinyl tubing. I obtain globes from lighting dealers. I am
also investigating the innards of an 'eye of the storm' to gain insight
into shrinking my own supply. My goal is a *large* aestheticly charming
globe on an unobtrusive pyramidal base and a ceiling high devil's
furnace.
Always wear safety glasses when working with this stuff.
Dave
