Title: Luminous radiation electron tube
Inventor: TOHO MAKOTO
IPC: H01J63/06
Filed: 1986-05-26
Abstract: PURPOSE:To improve the luminous efficiency, by forming an anode in a ring- form, while focusing electron beams in the anode ring by a static magnetic field generating source arranged at the rear side of a cathode on the line combining the center of the anode ring with the cathode, and dispersing them at the rear space of the anode. CONSTITUTION:A static magnetic field generating source 7 is arranged at the rear side of a cathode 2 on the line combining the center of an anode ring 3 and the cathode 2. Since the anode ring 3 is of a ring-form, the potential around the center is lower. The electrons which have passed through the cathode 2 have an energy determined by the electric field distribution when they pass through the anode ring 3. Therefore, by focusing the electron beams in the anode ring 3 by the static magnetic field generating source 7, the energy of the electron beams can be made lower. And since the magnetic field distribution is dispersed at the rear side of the anode ring 3, an even radiation can be obtained at the rear space 4. Furthermore, since the electrons which have passed through the anode 3 travel in the condition to wind around the lines of magnetic force B, the probability of striking the gaseous atoms is higher, and the luminous efficiency is also improved.
