Abstract: The present invention relates to a charged particle beam apparatus enabling a selection of a charged particle beam in a specified energy range by symmetrically arranging cylindrical electrostatic lenses deflecting a path of the charged particle beam and disposing an energy selection aperture between the cylindrical electrostatic lenses. Since an integral structure in which a central electrode and a plurality of electrodes that are arranged at a front portion and a rear portion in relation to the central electrode of a monochromator are fixed to each other through insulator, is applied, a mechanism for adjusting an offset with respect to an optical axis is simplified as compared to the case of separately providing the lenses at the front portion and the rear portion, respectively, and a secondary aberration is canceled in an exit plane due to symmetry of an optical system.

Abstract: In a MG control device, a standard voltage calculation part calculates a d axis standard voltage and a q axis standard voltage in a standard state in which no demagnetization occurs in permanent magnets of a MG. A magnetic flux change amount estimation value calculation part calculates a basic magnetic flux change amount estimation value based on a deviation of a specific value from the q-axis standard voltage. This specific value is obtained by multiplying q axis real voltage with a ratio of the d axis standard voltage and the d axis real voltage. A magnetic flux change amount estimation value correction part adjusts a magnetic flux change amount estimation value by correcting the basic magnetic flux change amount estimation value relatively to a detection threshold value based on characteristic change of the MG in a demagnetization state of the permanent magnets of the MG.
