Simple Electron Guns - Sources & Vacuum Storage Solutions

AI Thread Summary
Small electron guns are sought after for applications requiring vacuum storage, as traditional TV CRT guns fail due to filament exposure to atmosphere. Users are looking for affordable options, with one potential supplier being Kimball Physics, though their products may exceed a budget of $500. A general search for electron guns yields various results, but specific recommendations are limited. The challenge remains in finding a simple, cost-effective solution that can operate under vacuum conditions without compromising longevity. The discussion highlights the need for reliable sources and practical storage solutions for electron guns.

Does anyone know of a good source for small electron guns? Just a simple one. I was using a TV CRT gun but the filaments don't last when exposed to atmosphere. I obviously operate under vacuum but I have no way to store my device in a vacuum for a long period.

I googled electron gun buy, and got some reasonable hits. See if any would work for you:

The only supplier of them that I found was Kimball Physics, however those seem to be more complicated and advanced guns, which are most likely out of my ~500$ price range. I haven't received a quote from them as of now.
 

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
