ABSTRACT:
A beam deflector for scanning performs deflecting of a charged particle beam having a regular trajectory in a vacuum space to thereby periodically change the trajectory of the charged particle beam. The beam deflector comprises a pair of deflection electrodes disposed so as to confront each inner electrode surface having a symmetrical concave extending in a direction of a beam trajectory.
