-- Oh it leaves a lot to be desired. I have already thought of holes in it big enough to trive an 18 wheeler through. Thanks Richard.
>Great going Gerald! You have done everyone on this list a big favor! I have printed and GBC bound the entire site as a reference piece. Thanks also for noting the fusor tape in you refs.

--Don't mention it. Just covering my ass against charges of plagiarism. In all truth, I favor medieval remedies for that crime.

>As you know I have been stainless steeled with fuosr III since December 98.

--Duly referenced in my tech report, which is a bit more rigorous than the show and tell.
>I have not delved deeply into Gerald's material, but can tell it is good stuff and well thought out. Unfortunately not all the pix came over and showed a question mark in the file box at the upper left. I hope this is not my system. Let me know if other have trouble with these as it may be at Gerald's end.

--Let me know by all means! Ely Silk did but later got it allright. My server, AT&T has become too popular for my liking. They NEVER have enough resources these days! Be patient. Still, there probably is some rat killing to do there. I've never loaded any of my creations on the web without need for some correction.
>I thought of lost wax casting the grid system, I have a complete setup in my lab, but realized I would never get a grid system which would stand up to the heat.

--What have you been using for grid material lately? I would point out that the melting point of T-304 stainless is only 1800 F, merely 300 F above the denture alloy I used. Some alloys have melting points of 2700 F. (My old man used to use one.) If you have something that is tougher than that, pass it on. Mind you, the welding of such substances will be interesting. When I melt this cathode, I will be happy to report!

I figured if I had a way to melt the stuff, then the fusor would have it vaporized in seconds at high powers or during "runaway" events which are so common with low end vacuum setups. These occur when the emission of the grid at or near incandescense (electrons) can support huge currents on its own. With a fixed, non-current limited supply, this will vaporize a grid in seconds.

--Yep. Runaway is something all good fusorites should read up on. I recommend von Engle. I have had the stainless steel wire grid orange hot before. That was when I nearly burned through that bell jar. Neither Dr. Bickel or I know what that thing is made of, but I suspect it is boro-silicate. Ordinary glass probably would have busted on the spot.
>I'll probably comment more on this wonderful website as I dig into the material. Gerald can be very proud of the effort he has put into the project. Good luck at Rayheon.

-- Mou ichi do, arigato gozaimasu! The headhunters at my future employer liked my original web page enough to put me in the Electron-Optical section. I think they will dig my work in spectroscopy as much as the ion optics. When one of you all has the time, try my Gaussian torus solution to the ring of charge problem. then try deriving the elliptical integral, which is the canonical approach. Serendipity strikes again! I thought of the Gaussian "doughnut" after a run in with a cop....
