摘要

NUSES是一项计划中的太空任务,旨在测试与研究相对低能宇宙射线、伽马射线和高能天体物理中微子有关的新观测和技术方法。NUSES太空任务将搭载两个科学有效载荷:Terzina和Zirè。Terzina将是一个由SiPM阵列读出的光学望远镜,用于探测和研究由大气中的高能宇宙射线和中微子产生的广泛空气阵雨发射的切伦科夫光。Zirè将专注于检测高达几百MeV的质子和电子以及0.1-10 MeV的光子,并将包括低能模块(LEM)。登月舱将是一个粒子光谱仪,专门用于观测0.1 - 7 MeV范围内的相对低能电子和3-50 MeV范围内的质子沿低地球轨道(LEO)的通量,随后是宿主平台。在这个感兴趣的物理频道中探测粒子爆发(PBs)可以为理解复杂现象提供新的见解,例如地震事件或火山活动与填充范艾伦带的等离子体中粒子的集体运动之间的最终相关性。由于其紧凑的尺寸和有限的接受度,登月舱将允许探索恶劣的环境,如南大西洋异常区(SAA)和内部范艾伦带,其中预期的电子通量为每平方厘米每平方厘米每秒106到107个电子。关于天基粒子光谱仪的大量文献,LEM的创新之处在于它的紧凑性,在10 × 10 × 10 cm3以内,以及它的“主动准直”方法处理这些非常低能量的多重散射问题。在这项工作中,将介绍探测器的几何结构、探测概念、工作方式以及所采用的硬件。将显示蒙特卡罗模拟(Geant4)的一些初步结果。

A Compact Particle Detector for Space-Based Applications: Development of a Low-Energy Module (LEM) for the NUSES Space Mission
NUSES is a planned space mission aiming to test new observational and technological approaches related to the study of relatively low-energy cosmic rays, gamma rays, and high-energy astrophysical neutrinos. Two scientific payloads will be hosted onboard the NUSES space mission: Terzina and Zirè. Terzina will be an optical telescope readout by SiPM arrays, for the detection and study of Cerenkov light emitted by Extensive Air Showers generated by high-energy cosmic rays and neutrinos in the atmosphere. Zirè will focus on the detection of protons and electrons up to a few hundred MeV and to 0.1–10 MeV photons and will include the Low Energy Module (LEM). The LEM will be a particle spectrometer devoted to the observation of fluxes of relatively low-energy electrons in the 0.1–7-MeV range and protons in the 3–50 MeV range along the Low Earth Orbit (LEO) followed by the hosting platform. The detection of Particle Bursts (PBs) in this Physics channel of interest could give new insight into the understanding of complex phenomena such as eventual correlations between seismic events or volcanic activity with the collective motion of particles in the plasma populating van Allen belts. With its compact sizes and limited acceptance, the LEM will allow the exploration of hostile environments such as the South Atlantic Anomaly (SAA) and the inner Van Allen Belt, in which the anticipated electron fluxes are on the order of 106 to 107 electrons per square centimeter per steradian per second. Concerning the vast literature of space-based particle spectrometers, the innovative aspect of the LEM resides in its compactness, within 10 × 10 × 10 cm3, and in its “active collimation” approach dealing with the problem of multiple scattering at these very relatively low energies. In this work, the geometry of the detector, its detection concept, its operation modes, and the hardware adopted will be presented. Some preliminary results from the Monte Carlo simulation (Geant4) will be shown.
