Electron beam diodes with sharp edge cathodes and planar anodes of the type typically used for laser excitation are rather well understood and their performance may be characterized by a simple space charge limited flow model. The use of more complex geometry such as a diode with sidewalls or the addition of a magnetic field greatly complicates the situation. A computer code has been developed which simulates such diodes. The code has been used to investigate the effects of applying an external magnetic field on the electron flow pattern in the diode are detailed. Implications for the design of such diodes to meet applications where the survival of the anode foil is critical are discussed.
