 Abstract: Basic concepts are developed for realizing a cold, ultra-low energy, magnetically guided electron beam to serve as an electron cooler and an electron target for the electrostatic Cryogenic Storage Ring (CSR). The feasibility of ultra-low energy electron beams with sub-eV kinetic energy and densities sufficient for electron cooling and merged-beam collision experiments is demonstrated at the TSR electron target using a cryogenic electron source. A mechanical and magnetic system is laid out for implementing this ultra-low energy beam at the CSR. A new electron and ion beam merging scheme is developed and analyzed by numeric magnetic field and particle track calculations. The design concept of cryogen-filled HTS magnets was developed. For this purpose a prototype magnet was manufactured and tested under realistic operating conditions. A two-phase neon-based cryogenic low pressure cooling system to cool the magnets independent of the main CSR cooling machine was designed, constructed and successfully taken in operation. The reported work yields an experimentally tested design concept of the electron cooling system.
