Note (General): Workshop on research and development of JIEDI (JAXA Ion Engine Development Initiatives) tool for numerical evaluation of ion engine grid lifetime
PIC codes are suitable to evaluate numerical models for JIEDI tools. We have developed a hybrid-PIC code taking account of the charge exchange ions. In the present study, for the purpose of analyzing more realistic flows, the code was extended to allow elastic scattering ions and neutrals and to treat electrons as particles. Using the full-PIC code, we performed 3-dimensional analyses of the standard problem derived from the experiments using the uniform upstream and downstream conditions. As a result, the validity of the code was basically confirmed by the evaluation of energy flux distribution to the accelerator grid and the comparison between the results of ion-impingements current and the experiments.
