Most of the radiation measurements have been made onboard spacecraft flying along orbits with an inclination of up to 51.6 degrees. Due to the prospect of manned missions at orbits with larger inclinations, it is advisable to conduct preliminary detailed dosimetry measurements at a high-inclination orbit; due to its polar orbit, the Lomonosov satellite provides good opportunities for such study. We chose a method of cosmic radiation dosimetry based on semiconductor detectors. This method is widely used onboard spacecraft, including full-time radiation monitoring onboard the International Space Station (ISS). It should be noted that not only did the charged particles contribute significantly in the dose equivalent, but also did the neutrons. Semiconductor detectors have low sensitivity to neutron radiation and are not sufficient for detecting the expected flux of neutrons. We add a thermal neutron counter to the proposed device in order to provide an opportunity for estimation of neutron flux variations along the satellite trajectory.Thus, the design of the instrument DEPRON (Dosimeter of Electrons, PROtons and Neutrons) was determined. DEPRON is intended for registration of the absorbed doses and linear energy transfer spectra for high-energy electrons, protons and nuclei of space radiation, as well as registration of thermal neutrons. The present paper provides a brief description of the DEPRON instrument. Its calibration results and the first mission results of background radiation measurements are also presented.

使用Depron仪器进行辐射测量实验

大多数辐射测量是在沿轨道飞行的航天器上进行的,轨道倾角高达 51.6 度。由于在大倾角轨道上进行载人飞行任务的前景,建议在高倾角轨道上进行初步详细的剂量学测量;由于其极地轨道,罗蒙诺索夫卫星为此类研究提供了良好的机会。我们选择了一种基于半导体探测器的宇宙辐射剂量测定方法。这种方法在航天器上广泛使用,包括国际空间站(ISS)上的全时辐射监测。应该指出,不仅带电粒子对剂量当量有显着贡献,中子也有显着贡献。半导体探测器对中子辐射的灵敏度低,不足以探测预期的中子通量。我们在建议的设备中添加了一个热中子计数器,以便为估计沿卫星轨迹的中子通量变化提供机会。因此,确定了仪器 DEPRON(电子、质子和中子剂量计)的设计。DEPRON 用于记录空间辐射的高能电子、质子和原子核的吸收剂量和线性能量转移光谱,以及记录热中子。本文简要介绍了 DEPRON 仪器。还介绍了其校准结果和背景辐射测量的首次任务结果。我们在建议的设备中添加了一个热中子计数器,以便为估计沿卫星轨迹的中子通量变化提供机会。因此,确定了仪器 DEPRON(电子、质子和中子剂量计)的设计。DEPRON 用于记录空间辐射的高能电子、质子和原子核的吸收剂量和线性能量转移光谱,以及记录热中子。本文简要介绍了 DEPRON 仪器。还介绍了其校准结果和背景辐射测量的首次任务结果。我们在建议的设备中添加了一个热中子计数器,以便为估计沿卫星轨迹的中子通量变化提供机会。因此,确定了仪器 DEPRON(电子、质子和中子剂量计)的设计。DEPRON 用于记录空间辐射的高能电子、质子和原子核的吸收剂量和线性能量转移光谱,以及记录热中子。本文简要介绍了 DEPRON 仪器。还介绍了其校准结果和背景辐射测量的首次任务结果。质子和中子)被确定。DEPRON 用于记录空间辐射的高能电子、质子和原子核的吸收剂量和线性能量转移光谱,以及记录热中子。本文简要介绍了 DEPRON 仪器。还介绍了其校准结果和背景辐射测量的首次任务结果。质子和中子)被确定。DEPRON 用于记录空间辐射的高能电子、质子和原子核的吸收剂量和线性能量转移光谱,以及记录热中子。本文简要介绍了 DEPRON 仪器。还介绍了其校准结果和背景辐射测量的首次任务结果。
