Abstract
The Child‐Langmuir emission law is corrected to include magnetic field effects. The treatment is performed in local Cartesian coordinates near the cathode surface and all the terms obtained include first‐order relativistic effects. The effect of space charge flowing back to the cathode is also considered. The importance of using the corrected emission laws in the simulation of relativistic diodes is discussed.This publication has 4 references indexed in Scilit:
