Abstract
In the future Facility for Low-energy Antiproton and Ion Research (FLAIR) at GSI, the Ultra-low energy electrostatic Storage Ring (USR) will provide cooled beams of antiprotons and possibly also highly charged ions down to energies of only 20 keV/q. Beams with small momentum spread and low emittance will enable a wide range of hitherto impossible experiments. The large variety of planned experiments requires a highly flexible longitudinal time structure of the extracted bunches, ranging from ultra-short pulses in the nanosecond regime to quasi DC beams. In this contribution, a preliminary design of the extraction scheme is presented. Furthermore, possible solutions for the compensation of effects from the extraction region on the very-low energy beam are shown, including results from beam transport calculations.
