Re: questions about vacume tech

But that's exactly what a vacuum chamber is: a sealed container in which a vacuum is pulled using a vacuum pump.

Re: Idea for Rhodium Target

My guess is it's a flux but that implies sintering, which OP didn't mention doing.

Re: Anode layer ion source. Operation pictures

OK.

What would be the mechanism of failure? Heating the magnets to demagnetization?

Re: Other types of magnetron ion sources

I think "magnetron" has sometimes been used specifically to refer to the microwave generating tube, and sometimes to various devices that use both electrostatics and magnetics such as my sputter magnetron gun, which is related to a penning ion source but does not use penning configuration. I'm talki...

Re: Other types of magnetron ion sources

I'm talking about DC-only penning ion sources. Not a microwave magnetron.

Other types of magnetron ion sources

We've heard plenty about Andrew Seltzmann's very impressive and very advanced Anode Layer Ion Source. But I, a person with somewhat lesser abilties, am interested in building something a bit different. To be specific, I'm interested in a magnetron ion source (please forgive me if the ALIS isn't actu...

Re: Anode layer ion source. Operation pictures

Interesting that those Pasternack connectors work as high vacuum feedthroughs.

Can one realistically run one of these types of sources off an NST?

Re: Diffusion Pump

These are not terribly common, although KF flanged diffpumps in the smallest sizes definitely exist. These diffpumps are not particularly common, and tend to be expensive when you can find them. Most diffpumps you will find have a somewhat nonstandard "pipe flange" style flange on them, or maybe a s...

Re: dynamic fusor patent, Salvatore Pais

Before this kind of argument (which I don't quite agree with the conclusion of), it would seem like the hydrogen bomb, which we know all too well works reliably and tremendously effectively, is a kind of anomaly. It works reliably and quite effectively, though it requires a fission reaction to set i...

Re: Non-Corrosive and/or Dielectric Liquid Cooling?

Andrew, I'm curious about the details of the not-high-voltage portion of the fluorinert loop. It looks like you used a lot of swagelok - including teflon swagelok which I've never encountered before. Obviously in many cases (especially if using PC liquid cooling equipment) there's going to be plasti...
