国际空间站上剂量测量望远镜计数和剂量率的产额函数
Yield function of the DOSimetry TELescope count and dose rates aboard the International Space Station
摘要：
地球不断受到来自银河系的高能粒子的撞击。这些粒子的通量被日光层中磁化的太阳风和地球的磁场改变。因此，粒子接近近地轨道航天器的能力取决于其能量和航天器在地球磁层中的位置。此外，在某些区域（辐射带），粒子被长期捕获，因此高能粒子的通量特别高。有时，SEP也对高能粒子流有贡献。DOSTEL是\ac{ISS}上监测欧洲模块哥伦布内辐射场的仪器之一。由于安装在\ac{ISS}内部，“初级”辐射与国际空间站材料相互作用产生的粒子也被测量。为了描述在如此复杂的辐射场中的观测，我们遵循Caballero-Lopez和Moraal（2012）的方法，以便使用AMS获得的质子和氦能谱的精确测量值以及地球磁层内DOSTEL测量值的系统变化来计算所谓的屈服函数
英文摘要：
The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field. For this reason, the ability of a particle to approach a spacecraft in LEO depends on its energy and the position of the spacecraft within the Earth' magnetosphere. Moreover, there are some areas (radiation belts) where the particles are trapped for a long time, and therefore the flux of energetic particles is particularly high. Occasionally, SEP contribute to the energetic particle flux too. DOSTEL is one of the instruments aboard the \ac{ISS} that monitors the radiation field within the European module Columbus. Because being installed inside the \ac{ISS}, particles produced by the interaction between the "primary" radiation and the ISS materials are also measured. To describe the observations in such a complex radiation field, we follow the method by Caballero-Lopez and Moraal (2012) in order to compute the so-called yield function using precise measurements of the proton and Helium energy spectra obtained by AMS and the systematic variation of the DOSTEL measurements within the Earth's magnetosphere
