<p>PURPOSE:To reduce power consumed for stabilization of an electron beam orbit by covering a substrate surface between the anode and the cathode of an electron emission element with a high conductivity material and providing this substance and a substrate surface at the circumference of the electron emission element with specific surface resistance respectively. CONSTITUTION:A region of an electrode interval width W X an electrode interval G sandwiched in between an anode 2 and a cathode 3 is covered with a high conductivity material such that a surface resistance of approx. 1X10<4>-1X10<7>OMEGA/square is produced to form an electron emission section in the region of WXG. Moreover, the surface of a substrate 1 excluding the region of WXG is covered with high conductive material such that it becomes approx. 1X10<8>-1X10<10>OMEGA/square. Thereby, it is possible to reduce power consumption necessary for stabilizing the orbit of an electron beam emitted from a new surface conductive emission element.</p> |
