IPC: H01J1/15
Filed: 1981-09-24
Abstract: PURPOSE:To comparatively reduce a stationary operating temperature and emit a stable electron for a long period by constructing a cathode frame for an electron tube so that the cathode temperature can be kept in a specific higher temperature than the stationary operating temperature for a preset time after current is applied to the cathode and the cathode is heated and so that the cathode can be activated whenever power is supplied. CONSTITUTION:Materials with small resistivity and large temperature coefficient, for example, resistors 8 and 9 made of W, Mo, Ni, or the like are inserted between a cathode support 3 and a lead wire 6. These resistors are shaped into a coil form so as to be housed in a specified space with the length that is necessary for the required resistance value. Besides, the one resistor 8 between the support 3 and lead wire 6 winds a W wire round a core 7 consisting of ceramics such as alumina, forsterite, or the like. As a result, since an electron emission section 1 is kept in a higher temperature by 10 to 400 deg.C than the stationary operating temperature for a preset time and an oxide cathode is activated whenever power is supplied, the cathode capable of emitting electrons steadily can be obtained.
