Abstract:
1. A device for determining an aim position of a charged particle beam comprising: an adjusting unit that adjusts an irradiation position, in a depth direction of a subject, of an irradiation position determining charged particle beam irradiated from a charged particle beam source; a reflecting unit that transmits or allows the position determining charged particle beam to pass, and reflects a first emitted light emitted from a region of the subject on which the position determining charged particle beam is irradiated and a second emitted light emitted, due to an irradiation of an excitation light, from a region including the region of the subject on which the position determining charged particle beam is irradiated, toward the outside of the axis of the charged particle beam; and an imaging unit that is arranged at a position where the first emitted light and the second emitted light reflected from the reflecting unit are incident and images the region including the region of the subject on which the position determining charged particle beam is irradiated by allowing incidence of the first emitted light and the second emitted light.
