With an accelerator for accelerating an electron beam by a voltage of about 400 KV having a stability of 10-6, it is difficult to use a flexible, insulated cable to feed the output from a power supply to an electron beam and an accelerating tube. Accordingly, the present invention employs a rodlike connector instead of such an insulated cable. A guide means is provided to permit the movement of a power supply column in the direction of the axis of the connector. This facilitates cleaning or otherwise maintaining the power supply column, the electron gun, and the accelerating tube.
