摘　　要：A new extraction system is designed for a penning ion source DUHOCAMIS （dual hollow cathode ion source for metal ion beams） being installed at the Institute of Heavy Ion Physics,Peking University.We have analyzed theoretically the central particle trajectories in the extraction region for ions having different q/m ratios and then compared our results with the simulation results of CST （Computer Simulation Technology） software.The validity of the system is verified and some analytical formulas are obtained which will be used for the optimization of the extraction system as well as the experimental setup.A new extraction system is designed for a penning ion source DUHOCAMIS （dual hollow cathode ion source for metal ion beams） being installed at the Institute of Heavy Ion Physics,Peking University.We have analyzed theoretically the central particle trajectories in the extraction region for ions having different q/m ratios and then compared our results with the simulation results of CST （Computer Simulation Technology） software.The validity of the system is verified and some analytical formulas are obtained which will be used for the optimization of the extraction system as well as the experimental setup.
