XIAO：用于SVOM任务的软X射线望远镜
XIAO: a soft X-ray telescope for the SVOM Mission
摘要：
对伽马射线暴（GRB）的研究是拓展我们对一些天体物理和宇宙学现象认识的一个关键领域。SVOM是一项中法合作的任务，它将探测和快速定位伽玛暴，特别是高红移的伽玛暴，并研究它们的多波长发射。SVOM卫星将于2013年发射，将携带在X/伽马射线波段工作的宽视场仪器以及窄视场光学和软X射线望远镜。在这里，我们描述了一个小的软X射线望远镜（XIAO）提出作为意大利的贡献的SVOM任务。由于有一台有效面积约为120平方厘米、焦距短的掠入射X射线望远镜，再加上一台非常紧凑、低噪声、快速读出的CCD相机，XIAO可以为伽马射线暴和非伽马射线暴科学的整体SVOM能力做出重大贡献。
英文摘要：
The study of Gamma-ray bursts (GRBs) is a key field to expand our understanding of several astrophysical and cosmological phenomena. SVOM is a Chinese-French Mission which will permit to detect and rapidly locate GRBs, in particular those at high redshift, and to study their multiwavelength emission. The SVOM satellite, to be launched in 2013, will carry wide field instruments operating in the X/gamma-ray band and narrow field optical and soft X-ray telescopes. Here we describe a small soft X-ray telescope (XIAO) proposed as an Italian contribution to the SVOM mission. Thanks to a grazing incidence X-ray telescope with effective area of ~120 cm^2 and a short focal length, coupled to a very compact, low noise, fast read out CCD camera, XIAO can substantially contribute to the overall SVOM capabilities for both GRB and non-GRB science.
