Abstract

PURPOSE: More than 3 units of heating current leading legs are provided according to kinds of heating power source in order to make zero the current density at centeral area of electron radiation surface. In such a way, the axis slippage of beam can be avoided as well as a long life is ensured for hot cathode.
