Abstract:
A method and a device for stabilizing the emission current of an emitter of a charged particle beam device are provided. In the method, the emitter is operated under predetermined operation parameters including at least one voltage with a predetermined value. The method includes determining a first value of the emission current under the predetermined operation parameters and flash cleaning the emitter while a first electric field is applied to the emitter. The first electric field is generated by the at least one voltage having a first value of the at least one voltage, wherein the first value of the at least one voltage is provided in dependence of the determined first value of the emission current.
