Abstract
Ideal "waterbag" electron bunches - uniformly filled, hard-edged ellipsoids of charge - can be realized in practice by photoemission with properly shaped fs laser pulses [1]. The linear self-fields of such objects enable thermal-emittance-limited beams and bunch compression to the kA level. The thermal emittance may be lowered to below 0.1 micron by extracting the electrons from an ultra-cold plasma, created by photo-ionization of a cloud of laser-cooled atoms. We will present GPT simulations of the application of waterbags and cold atoms in realistic settings, based on established technology. The status of experiments will be reported.
