Abstract

In this paper, we present the results of Monte-Carlo simulations of the flux and energy spectra of neutrons generated as a result of galactic cosmic ray proton interactions with the material of International Space Station (ISS) inside Zvezda Service Module, the Airlock between Russian and USA segments and one of Russian Research Modules for a full configuration of ISS. Calculations were made for ISS orbit for the energy ranges <10 and >10 MeV for both maximum and minimum of solar activity. To test the accuracy of the calculations the same simulations were made for MIR orbital station and for CORONAS-I satellite and compared with the results of measurements. Calculated and measured fluxes are in reasonable agreement.

摘要

在本文中，我们展示了蒙特卡罗模拟的结果，该模拟针对国际空间站（ISS）全配置情况下，银河宇宙射线质子与星辰号服务舱、俄罗斯和美国舱段之间的气闸以及俄罗斯的一个研究舱内的物质相互作用所产生的中子通量和能谱。针对国际空间站轨道，在太阳活动最大和最小时，对能量范围小于10 MeV和大于10 MeV的情况进行了计算。为检验计算的准确性，对和平号轨道空间站和日冕 - I卫星进行了相同的模拟，并与测量结果进行了比较。计算通量与测量通量吻合良好。
