| مستخلص: | Development of MUSCAT (Multi-Utility Spacecraft Charging Analysis Tool) had started in November 2004 as a quantitative spacecraft charging analysis tool in Japan. In the middle of development term, the beta version of MUSCAT has been released on March 2006 as the first version of integrated software. The integrated GUI (Graphical User Interface) tool of MUSCAT, called 'Vineyard' had been developed, which conducts the MUSCAT simulation on local Windows (trademark) PC. Functions of 'Vineyard' have parameter input panels including 3D satellite model, data converter from parameters in the GUI format into those in the solver format. As the development of the physical functions, fundamental physical elements such as photoelectron emission, secondary electron emission, auroral electrons had been included. As a result, the solver enables fundamental charging analyses at GEO (Geostationary Orbit), LEO (Low Earth Orbit) and PEO (Polar Earth Orbit), which makes MUSCAT feasible for multi-utility use. Parallelization and tuning of the code have almost been achieved, and eight-CPUs (Central Processing Unit) parallel computation can calculate absolute potential of a large-scale satellite model in a half size of maximum computation region of 256 x 64 x 128 in two days. Experiments for the code validation were made at LaSEINE (Laboratory of Spacecraft Environment Interaction Engineering) in KIT (Kyushu Institute of Technology). Spatial distribution of electric potential around the electrode of a Langmuir probe and IV (Current-Voltage) characteristic curve were measured, and we had good agreement in experimental results and the numerical ones. These results show that the physical functions of MUSCAT simulate charging processes quite well. For a function of plasma plume analysis of the MUSCAT solver, we consider a model of active emission of ions, which employs a fixed analytical beam ion profile and electrons of Boltzmann distribution.
