Abstract

Maximum achievable intensity for lowenergyelectronbeams is a feature that is not very often compatible with lowenergyspread. We show that a proper choice of the source and the acceleration optics allows one to match them together. In this scheme, a GaAs photocathode excited by a single-mode infrared laser and adiabatic acceleration in fully magnetised optics enables the production of a low-energy-spreadelectronbeam with relatively high intensity. The technological problems associated with the method are discussed together with its limitations.
