摘要：
A cathode structure for an electron tube that includes a cathode sleeve, an upper heat radiation part blackened by the oxidation of the Cr contained therein in order to increase the rate of the heat radiation, a lower supporting part covered by a nickel layer for preventing the oxidation of Cr, and a cathode sleeve holder that is connected to the lower supporting part by resistance welding.
