I meant the ceramic disk holding the middle element of the einzellense.

I'm a bit unclear on how this very impressive system all goes together.

What's the white ceramic material?

I have a Pyrex cylinder chamber that I use for my sputter coater.

I achieve 1 micron pretty easily, and I think if I could just find my leak I would get to one millitorr. Grease and grinding is necessary to achieve this.

Apropos of being careful with oil burner transformers: I use an oil burner transformer for my system, and today I ran a long (hours) attempt at sputter deposition of aluminum. (I am still trying to ignore logic and common sense and do it without argon). My deposition was put to an abrupt stop when I...

As a boy, I once made a "putt-putt boat" from scratch out of wood and 1/8 inch copper tubing. In practice it was more like a "gurgle-gurgle boat", and very slow moving -- I think it was vastly oversized for the "engine" and the boiler was also oversized for the heat source -- at the very least, a mu...

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

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

OK.

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

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...

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