ELECTRON BEAM IRRADIATION DEVICE

摘要

PROBLEM TO BE SOLVED: To stably operate an electron beam irradiation device of a type having a single power supply and multiple accelerators while enabling simplification, miniaturization and weight reduction of the structure of a DC high voltage power source device, and preventing a surge voltage from one of electron beam accelerators from being transmitted to the power source device and the other electron beam accelerators. SOLUTION: A distribution device 30 by which an acceleration voltage Va outputted from the DC high voltage power source device 10 is divided by the number of plural electron accelerators 80 and distributed to the accelerators is provided between the power source device 10 and the accelerators 80. The power source device 10 is connected with the distribution device 30 by a DC high voltage cable 20 for guiding the acceleration voltage Va outputted from the power source device 10 to the distribution device 30, and the distribution device 30 is connected with each electron ray accelerator 80 by a DC high voltage cable 70 through which the acceleration voltage Va distributed by the distribution device 30 is guided to each accelerator 80. A surge blocker 60 for blocking the surge voltage generated at each accelerator 80 and transmitted through each cable 70 is provided between a common line 68 leading to the cable 20 inside the device 30 and each cable 70.
