A set of software tools based on Pierce theory and the Cutler-Hines approach for thermal velocity effects have been developed for the design of sheet-beam electron guns. The tools yield parameters for rudimentary gun geometry, which are further refined using the 2-D particle-in-cell code EGUN. Candidate designs for guns suitable for applications to high-power, high-frequency microwave sources have been obtained. The results indicate good potential for the use of sheet-beams to generate microwaves applicable to future accelerators
