Straight low energy beam transport for intense uranium beams

摘要

A new high current uranium ion source and dedicated Low Energy Beam Transport (LEBT) will be built at the GSI High Current Injector (HSI). This LEBT will be integrated into the existing complex which already comprises two branches. The paper presents the design and dynamics simulation using the TRACE-3D and TRACK code. The simulation results illustrate that this straight LEBT can transport uranium beams over a wide range of space-charge compensation, and can provide 15.4 (14.2) mA U~(4+) inside of the effective acceptance of the subsequent RFQ assuming the space-charge is compensated to 100% (95%).
