利用INTEGRAL/SPI研究太阳
Using INTEGRAL/SPI to study the Sun
摘要：
太阳高能粒子（SEP）事件是探测天体物理粒子加速的一个主要机会，它可以将空间粒子的现场测量与太阳大气中硬X射线（HXR）和γ射线发射粒子的遥感相结合。对于空间环境，SEP是最大的危害之一，特别是对于航天器和人类探索太阳系。不幸的是，我们目前对SEP的加速和运输的理解是薄弱的。随着太空时代的到来，我们增加对与SEP相关的物理机制的了解至关重要。在这方面，SEP服务器项目旨在建立一个在线服务器，向空间研究界提供SEP数据和有关的太阳电磁辐射观测。INTEGRAL/SPI获得了许多与SEP事件相关的X射线/γ射线耀斑的观测结果。为了使这些数据可用于SEP研究，我们进行了一项重大努力，通过蒙特卡罗模拟其BGO探测器对与选定SEP事件相关的几个耀斑的响应，来指定INTEGRAL的太阳观测条件。
英文摘要：
Solar energetic particle (SEP) events are a prime opportunity to probe astrophysical particle acceleration by combining in-situ measurements of particles in space with remote sensing of the hard X-ray (HXR) and γ-ray emitting particles in the solar atmosphere. For the space environment SEPs are among the biggest hazards, particularly for spacecraft and human exploration of the solar system. Unfortunately our current understanding of the acceleration and transport of SEPs is weak. With the increasing onset of the space age it is vitally important that we increase our knowledge of the physical mechanisms related to SEPs. In this direction, the SEPServer project aims at building an on-line server that will provide the space research community with SEP data and related observations of solar electromagnetic emission. INTEGRAL/SPI acquires observations from many X-ray/γ-ray flares associated with SEP events. To make this data accessible for SEP studies we have undertaken a major effort to specify the solar observing conditionS of INTEGRAL through Monte-Carlo simulations of its BGO-detector response for several flares associated with selected SEP events.
