Abstract

Over the past several years a great deal of progress has been made toward generating ultrashort electron pulses for a variety of applications,^1,2 such as LEEDS and the generation of ultrashort x-ray pulses. By using current technology, electron pulses in the 50-fs time range appear to be possible.¹ The electron pulse, with 0.5 eV of excess energy, has extent in space of the order of 0.5 µm for a 1-ps pulse.
