Jem-Euso任务

The Jem-Euso Mission

Yoshiyuki Takahashi, the JEM-EUSO Collaboration

摘要:

JEM-EUSO是一项空间科学任务,旨在探索宇宙的极端能量和物理学。它的仪器将观察地球的黑暗面,并将探测由超高能宇宙射线(10 ^18 eV以上的UHECR)或极高能宇宙射线(EHECR)粒子(例如,高于约10^20 eV)。像后者这样的高刚性粒子几乎是从它的起源通过我们银河系的磁场直线到达的,预计将使我们能够通过它的到达方向来追踪源位置。这种性质可以打开带电粒子新天文学的大门。在包括倾斜模式在内的五年运行中,JEM-EUSO将利用GZK截止光谱探测到至少1,000个E>7x10^19 eV的事件。它可以确定GZK到超GZK区的能谱和源位置,统计精度为百分之几。JEM-EUSO计划由氢转移飞行器(HTV)部署,并将连接到国际空间站的日本实验舱/曝光设施(JEM/EF)。日本宇宙航空研究开发机构已选定JEM-EUSO作为2010年代初至中期发射的JEM/EF第二阶段利用的候选飞行任务之一。

英文摘要:

JEM-EUSO is a space science mission to explore extreme energies and physics of the Universe. Its instrument will watch the dark-side of the earth and will detect UV photons emitted from the extensive air shower caused by an Ultra-High Energy Cosmic Rays (UHECRs above 10^18 eV), or Extremely High Energy Cosmic Ray (EHECR) particle (e.g., above about 10^20 eV). Such a high-rigidity particles as the latter arrives almost in a straight-line from its origin through the magnetic fields of our Milky Way Galaxy and is expected to allow us to trace the source location by its arrival direction. This nature can open the door to the new astronomy with charged particles. In its five years operation including the tilted mode, JEM-EUSO will detect at least 1,000 events with E>7x10^19 eV with the GZK cutoff spectrum. It can determine the energy spectrum and source locations of GZK to super-GZK regions with a statistical accuracy of several percent. JEM-EUSO is planned to be deployed by H2 Transfer Vehicle (HTV) and will be attached to the Japanese Experiment Module/ Exposure Facility (JEM/EF) of International Space Station. JAXA has selected JEM-EUSO as one of the mission candidates of the second phase utilization of JEM/EF for the launch in early-to-mid 2010s.
