日本Sprint-A小卫星上搭载的极端紫外线(EUV)望远镜EXCESS(Extreme UV Spectrcope For Exspere Dynamic)将于2013年8月发射升空。Beyond仪器将观测太阳系行星(例如水星、金星、火星、木星和土星)周围的稀薄气体和等离子体。Excade仪器的光谱范围为60-145 nm，光谱分辨率为0.4-1.0 nm。该仪器的视场为400“×140”(最大)，姿态起伏稳定在±5“以内。该仪器的光学部分包括直径200 mm的入射镜、三种类型的狭缝、两种滤光片、层流型光栅和带有电阻阳极编码器的五级微通道板组件。本文报告了该仪器的总体任务概况、仪器装置和地面标定结果。
The extreme ultraviolet (EUV) telescope EXCEED (Extreme Ultraviolet Spectroscope for Exospheric Dynamics) onboard the Japan's small satellite SPRINT-A will be launched in August 2013. The EXCEED instrument will observe tenuous gases and plasmas around the planets in the solar system (e.g., Mercury, Venus, Mars, Jupiter, and Saturn). The EXCEED instrument is designed to have a spectral range of 60-145 nm with a spectral resolution of 0.4-1.0 nm. The instrument has a field of view of 400” x 140” (maximum), and the attitude fluctuations are stabilized within ±5". The optics of the instrument consists of an entrance mirror with a diameter of 200 mm, three types of slits, two types of filters, a laminar type grating, and a 5-stage microchannel plate assembly with a resistive anode encoder. In this paper, we report the general mission overview, the instrumentations, and the results of ground calibrations.
