Generation of Cold Electrons for an eV Electron Cooler
Electron cooling of the antiproton beam will be essential to reduce or eliminate the emittance blow-up caused by the deceleration process and obtain the small emittance antiproton beam needed for further deceleration and extraction to the trap experiments. The electron gun must produce a cold (T^< 0.1 eV, T║ < 1meV) and intense electron beam (ne ≈ 1.5x1012 m-3).
Within this project options for a cold electron source will be studied, including expected performance and limitations and improve the understanding of cold electron beam generation. This will involve simulations into the cooler source performance and experimental studies that aim at a full characterization of the emitted electron beam.
