Re: Titanium Coated Endcaps for the Cube Fusor
Jon, Jim, Richard
Thanks for your comments.
Being unable to assembly a PVD, what about heating a titanium wire in a high vacuum, as in sublimation pumps?
Some will condense in an adecuately positioned piece.
Am I wrong?

Jon
A superb setup, as always.
But help me to understand. Wasn´t enough to use a titanium sheet?

info about TPH-050
I have the following questions about the Pfeiffer TPH-050 turbomolecular pump:
-where to get the lubricating oil, or a replacement one.
-the resistances of the motor windings.
-the motor windings pin-out.
Thanks in advance.

Experimental techniques
I wish to call your attention to a nice bibliography on experimental techniques, not all but many ones useful for fusor experimenters:
Experimental Innovations in Surface Science, by John T. Yates Jr.
The title is slightly misleading but the content is invaluable.

I am a bit confused about the image of your HV feedthrough.
The CF flange (a Varian one) seems to lack the sharp edge to seal against the copper washer.
Please comment.

Re: Window dressing - Trying to clean view port glass
Hi Richard, a useful technique to removing tungsten deposits is melting a bit of sodium nitrite over the surface to be cleaned. It melts at low temperature and reacts with the tungsten. Then you wash thoroughly the window with distilled water.

Hi Patrick
Thanks for sharing.
Not useful for my project but a friend of mine, in struggle with an electrostatic accelerator will enjoy your info.
