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 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
