成ることを特徴とする治療用線形電子加速装置。[Claims for Utility Model Registration] Includes an accelerator that accelerates an electron beam, and a movable target made of heavy metal that converts the electron beam accelerated by the accelerator into X-rays, and moves the movable target into and out of the path of the electron beam. A therapeutic linear electron accelerator capable of irradiating two types of radiation, X-rays and electron beams, includes a target position detector that detects the position of the movable target, and a target that drives the movable target to move it into and out of the trajectory of the electron beam. A signal for driving the target according to the radiation type set by the drive circuit and the operator is output to the target driving circuit, and the target drive circuit determines whether the movable target is at the position to be set according to the selected radiation type. If the target position does not correspond to the selected radiation type as determined by the signal from the position detector, or if the target position detector is malfunctioning or the target drive circuit is malfunctioning, radiation irradiation will be stopped. A linear electron accelerator for treatment, comprising: a controller for inhibiting.
