Buy High Voltage Electron Guns Up to 40kV - Expert Advice

Click For Summary

Discussion Overview

The discussion revolves around seeking recommendations for companies that sell high voltage electron guns up to 40kV. Participants explore various options, including unconventional methods of obtaining electron guns and the associated costs.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant requests recommendations for companies selling high voltage electron guns up to 40kV.
  • Another participant suggests that a cost-effective method to obtain an electron gun could be to salvage one from a TV tube, assuming the requester has the necessary high vacuum manufacturing facility.
  • A participant mentions having seen an advertisement for electron guns ranging from 1-100 keV in a physics magazine and provides a link to a company, though they do not personally recommend it.
  • There is a reiteration of the advertisement for electron guns, with a note that they appear to be expensive, contrasting with the idea of a low-cost solution.
  • A later reply expresses appreciation for the information shared and indicates a shared interest in low-cost options.

Areas of Agreement / Disagreement

Participants express varying opinions on the best approach to acquiring an electron gun, with some favoring low-cost solutions while others point to more expensive commercial options. No consensus is reached on a definitive recommendation.

Contextual Notes

Participants do not clarify the specific requirements or applications for the electron guns, nor do they address the technical specifications needed for compatibility with different setups.

Hi folks,

In need of some advice.

Can anyone recommend any companies selling high voltage electron guns up to 40kV?

Thanks!

I should have thought the cheapest way to go about getting an electron gun would be to buy a TV tube (even a scrap one) and remove the gun from it. If you are after an electron gun, it must be assumed that you have a high vacuum manufacturing facility for mounting it in whatever electron beam tube you are planning to make. Are you sure this is what you want?
 
Saw an ad for 1-100 keV guns in last month's physics world mag... let me dig it out

can't personally recommend it but it rang a bell so I thought I'd post it

Looks like well expensive pieces of kit. I was thinking of the 'crud end of the market' solution!
 
Haha! Thanks very much for your help guys.

I was thinking the crud end of the market too but its good info to know. thanks for that.
