AN ELECTRON COOLING SYSTEM FOR THE PROPOSED HESR ANTIPROTON STORAGE RING
2004
The availability of antiprotons with high beam quality in the energy range 0.8-14.5 GeV in the storage ring HESR will be one of the features of the new FAIR accelerator facility. For the achievement of an excellent quality of the antiproton beam it is proposed to apply electron cooling. The electron cooling system will be based on an electrostatic acceleration system. The intense electron beam must be recovered with high efficiency. For the achievement of highest cooling rates the electrons will interact with the circulating antiproton beam in a 30 m long cooling section with a superimposed longitudinal magnetic guiding field of up to 0.5 T. Various novel techniques will be applied to achieve the required cooling performance in the high energy regime.
