Abstract
PURPOSE: To suppress the scatter and evaporation of electron emitting material and thus achieving long life, by coating the electron emitting material only on the intermediate one of the inside coils.
CONSTITUTION: The electrode is constructed from an inside coil 7, an outside coil 8 surrounding said coil 7, and an electrode rod 9. The inside coil 7 comprises thress partial coils each consisting of a multiple coil more than triple, and provided on the electrode rod 9 from its forward end toward its backward end along the axis thereof are three partial coils, that is, a multiple coil 7a more than triple with no electron emitting material being coated thereon, a multiple coil 7b more than triple with an electron emitting material being coated thereon, and a multiple coil 7c more than triple with no electron emitting material being coated thereon.
