    Abstract: PROBLEM TO BE SOLVED: To provide a method for operating an electrically-charged particle beam irradiation device including a cold cathode field emitter with an emitter face, especially an electronic beam irradiation device. SOLUTION: A cold cathode field emitter is located in vacuum which provides high initial irradiation current and low stabilized average irradiation current under a given extraction electric field (a). The extraction electric field is applied to the cold cathode field emitter in order to irradiate an electron from the emitter face, and the irradiation current of the cold cathode field emitter is made higher than the stabilized average irradiation current (b). A cleaning process is performed by heating the emitter face up to the predetermined temperature through application of at least one heating pulse, and such a process is carried out before the irradiation current of the cold cathode field emitter drops to the low stabilized average irradiation current (c). The cleaning process (c) is repeated to ensure that the irradiation current of the cold cathode field emitter continuously exceeds the stabilized average irradiation current (d).
