Title:
ELECTRON BEAM GENERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/021802
Kind Code:
A2
Abstract:
The present invention relates to an electron beam generating apparatus capable of reducing the emittance of an electron beam. For this purpose, the electron beam generating apparatus according to the present invention comprises: a housing having a rear surface portion for generating an electron beam, a front surface portion having an electron beam emitting hole for emitting the generated electron beam to the outside, and a side surface portion for interconnecting the rear surface portion and the front surface portion, wherein the side surface portion has a first hole, and the opposite side surface portion facing said side surface with the first hole has a second hole to reduce an electric field imbalance caused by the first hole; and a waveguide arranged at the side surface portion to supply electromagnetic waves into the housing through the first hole. The laser beam applied into the housing generates an electron beam, and the thus-generated electron beam is accelerated by the electromagnetic waves supplied into the housing.
