Abstract:
To suppress both influence of electron emission from a cathode side surface and consumption of energy to be supplied to a heater, while being provided with a grid, an electron gun of the present invention includes: a cathode capable of emitting electrons by heating; a grid capable of controlling the electron emission; and a cathode shield which is an conductor including a material portion located in the vicinity of a side surface of the cathode and facing at least a portion of the side surface via a gap or a heat insulating material, and not being made in direct physical coupling nor in direct physical contact with the cathode.

Claim (Index 2):
The electron gun according to  claim 1 , wherein the cathode shield is provided with an electric potential equal to or lower than a first electric potential, the electric potential being an electric potential approximately equal to an electric potential provided to the cathode.
