摘要
A Penning surface H- ion source test stand has been developed for the China Spallation Neutron Source (CSNS) at the Institute of High Energy Physics (THEP). H- beams with a current up to 50 mA and a pulse length up to 520 mu s at a repetition rate of 25 Hz are obtained at present. In order to improve the extraction system based on both the results of the emittance measurements in experiment and the simulation results of the effect of the extraction system on the beam emittance, three dimensional electromagnetic finite element analysis and particle tracking are undertaken. First, the magnetic field of the deflecting magnet is studied in detail, and then the effect of the extraction geometry on the beam transport is also investigated.
