Abstract :
The operation of a DC recirculation electron beam system is described. This system is a prototype for intermediate energy electron coolers, capable of cooling particle beams in the energy range between γ=2 and γ=20. In addition, this system can be altered to provide DC FEL (free-electron laser) radiation in the submillimeter wavelength region with average power output of 10 kW or greater. Ampere intensity beams with minimal losses now appear attainable, as the present system has been run at currents greater than 100 mA with losses of about 10 μA. This corresponds to a combined beam transmission and collection efficiency of better than 99.99%
