Electron Guns

  • #1
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.

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.
