Near Field Evaporative simulation update.


James Lerch
 

Greetings All,

Thanks to Peter Baird, I've added the option in my simulation code to
support multiple evaporating rings. An interesting result from this
experiment shows that it should be feasible to construct a 12" diameter by
5" tall chamber. The downside of course is the need for 19 separate
tungsten evaporating coils!

While this might not be feasible for such a small chamber, when constructing
my next chamber (20-30" diameter) it might just be worth the effort! The
main benefit of such a short chamber would be the reduction in chamber
volume, thus allowing the use of smaller pumps and faster pump down time!

To implement such a wiring nightmare might be interesting, but I'm wondering
if I might be able to mass produce some Ceramic electric pass throughs.
Something that would just require drilling a hole in the chamber, then drop
the pass thru in, and seal with an O-ring.. (still working out the details
:) Anyone ever seen anything like this?
