RF Gun

The RF Gun uses microwave energy to produce and accelerate electrons in a high electric field.

AET has researched and developed various RF Guns such as a RF Gun with a thermionic cathode, a triode type RF Gun and a Micro Miniature RF Electron Gun using a coaxial resonator.

The triode RF Gun is an epoch-making product which is able to eliminate the back bombardment phenomenon, reduces emittance of the electron beam, and enables control of pulse width simultaneously.

The novel Micro Miniature RF Gun with a diameter of 5mm can be used as an electron or X-ray source for industrial and medical applications.
