摘要
针对空间带电粒子各向异性分布,不同的入射方向,粒子的通量有数个量级的差异,提出安装在二期载人航天目标飞行器上的新一代空间粒子探测器——空间粒子方向探测器。该仪器为我国最新研制的多功能、小型化空间带电粒子探测器,首次实现了高能电子、质子能谱探测及180°方向的粒子通量测量。通过监测轨道空间各种带电粒子的区域分布、方向分布和能谱分布,以及时空变化,从而获得完整的空间高能带电粒子的辐射图像,建立载人航天轨道静态和初步动态粒子辐射模型。
A Particles＇ Direction Detector （PDD） on manned space II is proposed for some theories on space science that high energy particles are anisotropy and exploration results from satellites that particles＇fluxes may vary from several magnitudes with their different injecting directions. The instrument firstly integrates high ener- gy electrons＇and protons＇directions, spectrums and fluxes measurements together. From observing high energy particles＂ regional distribution, direction distribution, spectrum distribution and temporal and spatial variation, we can acquire high energy particles＇radiation graphics, thus build static and preliminary dynamic particles＇radiation models.
