Abstract:
A method of adjusting characteristics of an electron generating apparatus having a multi-electron-beam source in which a plurality of surface-conduction emission devices are arranged on a substrate, each of the plurality of surface-conduction emission devices emits electrons by applying a driving voltage, comprising the steps of:applying a characteristic measuring voltage to measure the characteristics of said plurality of surface-conduction emission devices; obtaining a reference value of the characteristics of said plurality of surface-conduction emission devices on the basis of the measured electron-emitting characteristics; and applying a characteristic shift voltage to a corresponding one of said plurality of surface-conduction emission devices such that the electron-emitting characteristics of said plurality of surface-conduction emission devices become values according to the reference value, wherein the characteristic shift voltage is higher than the characteristic measuring voltage, and the characteristic measuring voltage is higher than the driving voltage.
