%X The space plasma detector is a kind of cylindrical electrostatic analyzer with the field of view larger than 320° and the capability of measuring the plasma of 10eV～30keV. The basic parameters of the plasma detector, such as the electrostatic analyzer factor, energy resolution and the relationship between the deflection factor and the deflection angle, were simulated by the software SIMION. The particle source for the simulation was constructed by the method of uniform random sample. The simulation results fit well with the calibration results. The error between the simulation and the calibration on the parameters of electrostatic factor and energy resolution are 3.2% and 1.5%, respectively. The correlation coefficient between the simulation and the calibration on the relationship of deflection angle and deflection factor is 0.9994. he simulation results show that it can be applied well in the process of plasma instrument design and calibration.
