Abstract

PURPOSE:To minimize flection of a slender tube by heating a heating unit at high frequency in vacuum to sputter a material to metallize and preparing a cathode area large enough through forming a metallized cathode. CONSTITUTION:A mask 8 is mounted on the portion 1'-1'' of a slender tube 1, a material to metallize in a heating unit 9 is inserted in a shroud 2, the heating unit 9 is heated at high frequency in vacuum, the material 10 is thus sputtered to form a metallized cathode 6, which is connected to electrodes 5, 5'. After that, the heating unit 9 is extracted, and a connection 2' for shrouds 2 and 2'' is connected to complete the shroud 2. In case the center of the slender tube 1 is supported with a wall 3, an area of the cathode 6 can be taken large enough, and hence a flection of the slender tube 1 is minimized, which is thus given in a stable position to work for stable output.
