Computer simulation of electron beams interacting with electromagnetic pulses generated in internally switched cavities is presented. The formulation and properties of the algorithms for the electromagnetic field propagation and particle motion are given. Results are shown for coaxial geometry, first showing the electromagnetic pulse propagation properties in the absence of a beam and then the interaction with a beam. The calculated accelerated beam has a risetime of a fraction of a nanosecond and the quality of the accelerated beam depends critically on the synchronization of the beam with the electromagnetic pulse. The limitations of the present version of the computer code and the directions for future work are discussed. A users guide for the code is provided as an appendix. Author
