| Abstract: | The beam current characteristics of a two component space-charge diode under the effect of electron injection with initial energy are studied. The diode is divided into two regions, by solving Poisson equations in the two regions, to yield analytical expressions for space charge limited electron/ion beam current densities of non relativistic one dimensional slab two component fluxe diode as a function of the initial energy of electrons emitted from the cathode, and compared with these results of zero initial energy of electrons, the results show that the two component space charge limited current densities decrease as the initial energy of electrons increase. |

| Keywords: | space charge limited current diode two component fluxes initial energy of electron |
