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?

Looks like well expensive pieces of kit. I was thinking of the 'crud end of the market' solution!
