You'll need to be a little more specific about you are looking for because any decent electronics store still sells TVs that use an electron gun.
Astronuc said:Normally, one would not use an electron gun to neutralize on ion beam. One uses a neutralizer that recombines the electrons from the ion source with the ions. This is the principle behind a neutral beam injector.
Ions will only remain ions in a vacuum, and on earth, that would in a vacuum chamber containing the ion source, which would mean that the electrons from those ions are somewhere nearby (usually).
Ah - ok. Some use trailing electrodes, others some kind of injector.PCLNuclear said:Yes, this is my idea. I wish to neutralise the ion beam coming out of an ion thruster. Could you please give me a little more light on the subject Astronuc?

Here's one using an injector.

Electron guns can be purchased from a variety of sources, including online retailers, specialized scientific equipment suppliers, and directly from manufacturers. It is important to do some research and compare prices and specifications before making a purchase.
The cost of electron guns varies depending on the type, specifications, and brand. On average, they can range from a few hundred dollars to several thousand dollars. It is important to consider your budget and research thoroughly before making a purchase.
Yes, you can purchase used electron guns from various sources such as online marketplaces, scientific equipment auctions, or directly from other researchers or institutions. It is important to thoroughly inspect the equipment and ask for any necessary documentation before purchasing a used electron gun.
In most cases, no special licenses or permits are required to purchase electron guns for scientific research purposes. However, it is always best to check with your local authorities to ensure that there are no specific regulations or restrictions in your area.
Yes, electron guns can emit high-energy beams and can be dangerous if not handled properly. It is important to follow all safety precautions and instructions provided by the manufacturer when purchasing and using electron guns. Additionally, it is recommended to have proper training and knowledge before operating these devices.
