Abstract
The present disclosure relates to a device for closing and opening a beam path of electromagnetic and/or ionizing radiation, comprising at least one part of a shutter body which is permanently situated in the beam path and rotatable about a longitudinal axis situated essentially transversely with respect to the beam path, and which contains a material that is opaque to the radiation and blocks the beam path when the shutter body is in a closed rotary position, and which defines a passage that is transparent to the radiation when in an open rotary position; and comprising a magnetic drive which is coupled to the shutter body for rotation of same about the longitudinal axis between the rotary positions. The magnetic drive is an electromagnetic drive, and is configured for moving the shutter body between the rotary positions, wherein at least one of the rotary positions corresponds to a stable position of the magnetic drive which maintains the magnetic drive without current.
