Abstract： The Neutral Atom Image System with High energetic particles (NAIS-H) developed for a Chinese mission of Magnetosphere Ionosphere and Thermosphere (MIT) capable to obtain the global map of the plasma distribution with a high temporal-spatial resolution in support this mission. The calibration of detector was an important technical task in the development, which is the fundamental basis of data analysis and inversions.

Abstract： Long term high energy electron irradiation may affect performance of the Si-PIN semiconductor detector (SSD).In order to assess the life of the detector in space radiation environment, electron irradiation source was used to simulate space electron environment, and the irradiation experiments were carried out on the semiconductor detector. Experiment results show that under the radiation dose of 7.64×1014, the SSD’s energy response capability had not changed, and the counting efficiency slightly decreased. As the radiation dose increased, the leakage current of the SSD increased, but the noise was relatively stable, and the performance of the detector did not affect the work index of the load.

Abstract： This paper introduces the structure and working principle of the Neutral Atom Imaging System-High （NAIS-H） which is in the MIT project. Based on the testing needs of the instrument， we have designed ground test equipment， including the circuit system and the host computer system. In this paper， we show the structure and working principle of the ground test for NAIS-H， and tell structure and java programming of the sub modules of the host computer system in detail， such as API communicating system， data analyzing system and data saving system. At last， we test the equipment， and the result shows the ground test system has good performance and achieves the design requirement.
