Abstract
A gap is provided between a cooling blockand a magnetic yoke. A cushioning materialis interposed in the gap to fix the cooling blockrelatively to the magnetic yokeby screws. Thus, even when metals having a large difference in tendency of ionization are used in the cooling blockand the magnetic yoke, the corrosion of the metals hardly arises. Further, the cushioning materialis provided in the gap between the cooling blockand the magnetic yoke, so that an impact or vibration to an anode tubular membercan be mitigated and the disconnection and deficiency of the filament of a cathode structural member can be reduced. Further, since a dimensional unevenness of the cooling blockor the magnetic yokecan be absorbed by the cushioning material, the dimensional accuracy of parts does not need to be improved to make an assembly easy.
