Magnetron injection gun having a structure of double anode

摘要

An object of the present invention is to provide a magnetron injection gun (MIG) capable of stably controlling an electric field around an emitter with a separate anode. The magnetron injection gun (MIG) according to an embodiment of the present invention can stably control the characteristics of the electron beam by finely adjusting the electric field around the emitter through the separate anode. In addition, the magnetron injection gun according to another embodiment of the present invention may be applied to a triode type so as to finely control the electric field around the emitter through a separate modulating anode, thereby effectively controlling the characteristics of the electron beam .
