Abstract

PURPOSE:To obtain a highly accurate assembling structure with low cost, by forming the end shield in circular with a metal wire having high melting point. CONSTITUTION:The upper end shield 7 formed in circular with a metal wire having high melting point such as molybdenum has the inner diameter approximately the same with the outer-diameter of cathode 5. While the lower end shield 8 formed in circular with a metal wire having high melting point such as molybdenum has also the inner diameter approximately the same with the outer-diameter of the cathode 5. The cathode 5 is formed such that the both end sections 5a,5b are linear and in parallel with a center support 1 in the same direction. Then the securing is performed with a brazing material 6 having high melting point between the tip section of the center support 1 and the central section 7a of the upper end shield 7, the upper end 5a of the cathode 5 and the inner wall of the upper ene shield 7, the lower end 5b of the cathode 5 and the inner wall of the lower end shield 8, and the outer-wall of the lower end shield 8 and the tip section of the side support 4.
