Abstract
Provided is a charged particle beam radiation control device that controls radiation of a charged particle beam, the charged particle beam radiation control device including: a controller which controls an acceleration voltage for accelerating charged particles, wherein the controller includes a set acceleration voltage controller which selects a non-radiation state of a charged particle beam by setting an acceleration voltage of a radiation state of the charged particle beam to a reference acceleration voltage and changing the acceleration voltage to a set acceleration voltage larger or smaller than the reference acceleration voltage.
