A design is proposed and the results of a numerical simulation of the extraction system for the source of negative hydrogen ions being developed at the IAP NAS of Ukraine are presented. The simulation was carried out with the help of the developed computer program using the possibilities of the freely distributed IBSimu package. The technique of modelling this system is described in detail. An analysis of the power distribution released in the electron beam dump is made. The dependence of the normalized emittance of the H ˉ ion beam at the exit of the extraction system via ion current is studied. The obtained results are explained in terms of the curvature of the plasma boundary and the method for minimizing the emittance over a wide range of ion current is proposed. |
