Where to buy high voltage electron guns up to 40kV?

[strokebow]

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!
