Abstract

The stringent requirements placed on the design of the electron beam absorber of high-average-power electron accelerators by applications such as the ground-based free-electron laser are discussed. Preliminary design characteristics of a rotating electron-beam absorber made of graphite, which operates in a stored energy mode, are presented. The thermophysical and mechanical properties of graphite make it a suitable material for this application. Several features are incorporated in the design to minimize radiation levels resulting from operation
