摘要

本文介绍了下一代小卫星1号(NEXTSat-1)卫星上空间辐射探测器(SRDs)的观测结果。SRDs是稳定/风暴时间空间研究仪器(ISSS)的一部分,由中能粒子探测器(MEPD)和高能粒子探测器(HEPD)组成。MEPD可以检测能量在20到400 keV之间的电子、离子和中性,HEPD可以检测能量在0.35到2 MeV之间的电子。在本文中,我们报告了一个事件,在数十keV能量的MEPD A观测中,由于亚暴注入而引起的粒子通量增强被清楚地识别出来。此外,我们报告了一个在宽能量范围内的电子分布的具体示例观察,其中我们确定了狭缝区域和外辐射带中来自MEPD的能量为数十至数百keV的电子空间分布,以及来自HEPD的能量高达几MeV的电子空间分布。此外,在1.5年的时间里,我们证实HEPD成功地观测到众所周知的外辐射带电子通量分布及其时间和L壳层的变化,与地磁扰动水平一致。最后,我们发现外辐射带的内缘与L中的等离子体顶位置基本一致,在亚相对论性能量下比在相对论性能量下更一致。基于这些例子事件,我们得出结论,SRD观测具有可靠的质量,因此它们有助于理解磁层内部的动力学,包括亚暴和辐射带的变化。

A Substorm Injection Event and the Radiation Belt Structure Observed by Space Radiation Detectors onboard Next Generation Small Satellite-1 (NEXTSat-1)
In this paper, we present observations of the Space Radiation Detectors (SRDs) onboard the Next Generation Small Satellite-1 (NEXTSat-1) satellite. The SRDs, which are a part of the Instruments for the study of Stable/Storm-time Space (ISSS), consist of the Medium-Energy Particle Detector (MEPD) and the High-Energy Particle Detector (HEPD). The MEPD can detect electrons, ions, and neutrals with energies ranging from 20 to 400 keV, and the HEPD can detect electrons over an energy range from 0.35 to 2 MeV. In this paper, we report an event where particle flux enhancements due to substorm injections are clearly identified in the MEPD A observations at energies of tens of keV. Additionally, we report a specific example observation of the electron distributions over a wide energy range in which we identify electron spatial distributions with energies of tens to hundreds of keV from the MEPD and with energy ranging up to a few MeV from the HEPD in the slot region and outer radiation belts. In addition, for an ~1.5-year period, we confirm that the HEPD successfully observed the well-known outer radiation belt electron flux distributions and their variations in time and L shell in a way consistent with the geomagnetic disturbance levels. Last, we find that the inner edge of the outer radiation belt is mostly coincident with the plasmapause locations in L, somewhat more consistent at subrelativistic energies than at relativistic energies. Based on these example events, we conclude that the SRD observations are of reliable quality, so they are useful for understanding the dynamics of the inner magnetosphere, including substorms and radiation belt variations.

期刊介绍: JASS aims for the promotion of global awareness and understanding of space science and related applications. Unlike other journals that focus either on space science or on space technologies, it intends to bridge the two communities of space science and technologies, by providing opportunities to exchange ideas and viewpoints in a single journal. Topics suitable for publication in JASS include researches in the following fields: space astronomy, solar physics, magnetospheric and ionospheric physics, cosmic ray, space weather, and planetary sciences; space instrumentation, satellite dynamics, geodesy, spacecraft control, and spacecraft navigation. However, the topics covered by JASS are not restricted to those mentioned above as the journal also encourages submission of research results in all other branches related to space science and technologies. Even though JASS was established on the heritage and achievements of the Korean space science community, it is now open to the worldwide community, while maintaining a high standard as a leading international journal. Hence, it solicits papers from the international community with a vision of global collaboration in the fields of space science and technologies.
