    Abstract: Cathode comprising a substrate (2) supporting a cathode emissive coating, comprising what is called an emissive central zone (12) and what is called a nonemissive peripheral zone (11); according to the invention: the average density and the emissive zone (12) is greater than that in said nonemissive zone (11), the average thickness in the emissive zone (12) is less than that in the nonemissive zone (11). In this way it is possible to significantly limit the drift in cut-off voltage, while still maintaining good maximum emission performance in DC mode and in pulse mode.

    Abstract: The present invention realizes a cathode ray tube which holds the stable electron emission characteristics when the cathode ray tube is operated in a high current density state for a long time. An electron emissive material layer which constitutes a cathode is formed by dispersing a scandium compound having an average particle size of equal to or less than 1.2 nullm to an oxide layer formed of alkaline earth metal (barium, strontium, calcium) oxide, wherein an atomic weight ratio of scandium with respect to strontium is set to a value within a range of 0.003 to 0.3. A base metal includes a reducing metal containing nickel as a main component and a plate thickness of a surface of a top portion of the base metal which comes into contact with the electron emissive layer is set to a value equal to or more than 0.17 mm.
