JEM-EUSO的物理目标、现状及测试实验

Physics Goals and Status of JEM-EUSO and its Test Experiments

Andreas Haungs, JEM-EUSO Collaboration

摘要:

JEM-EUSO飞行任务旨在通过观测来自空间的空气簇射荧光来探索极端能量宇宙射线的起源。这架超宽视场望远镜从国际空间站向下俯瞰夜空,探测空气簇射发射的紫外光子(荧光和切伦科夫光子)。这种空间探测器提供了一次观测大量大气的绝佳机会,并将在运行几年内实现前所未有的统计数据。目前正在进行几项试验:例如,一个用于观测大气层边缘的荧光背景(EUSO-气球),另一个用于在地面演示用EUSO型望远镜探测空气簇射的能力(EUSO-TA)。本文将简要回顾飞行任务的科学目标,更新仪器的定义、性能和状况,以及测试实验的状况。

英文摘要:

The JEM-EUSO mission aims to explore the origin of the extreme energy cosmic rays (EECRs) through the observation of air-shower fluorescence light from space. The superwide-field telescope looks down from the International Space Station onto the night sky to detect UV photons (fluorescence and Cherenkov photons) emitted from air showers. Such a space detector offers the remarkable opportunity to observe a huge volume of atmosphere at once and will achieve an unprecedented statistics within a few years of operation. Several test experiments are currently in operation: e.g., one to observe the fluorescence background from the edge of the Atmosphere (EUSO-Balloon), or another to demonstrate on ground the capability of detecting air showers with a EUSO-type telescope (EUSO-TA). In this contribution a short review on the scientific objectives of the mission and an update of the instrument definition, performances and status, as well as status of the test experiments will be given.
