微型X射线太阳光谱仪(MinXSS)是两颗3U立方体卫星。2015年12月向国际空间站发射的第一颗立方体卫星(MinXSS-1)将于2016年年中部署。两颗MinXSS CubeSats都使用了Amptek的商用现成(COTS)X射线光谱仪来测量0.5至30keV的太阳辐照度，标称为0.15keV的半高宽光谱分辨率为5.9keV，以及LASP开发的具有类似光谱灵敏度的X射线宽带光度计。MinXSS的设计和开发涉及40多名研究生，他们由科罗拉多大学博尔德分校的教授和专业人员指导。以前的大多数太阳软X射线测量要么是以窄带通的高光谱分辨率进行的，要么是光谱积分(宽带)光度计。MinXSS将在相对较大的能量范围内以中等光谱分辨率进行独特的软X射线测量，以研究太阳活动区的演化、太阳耀斑以及太阳软X射线发射对地球电离层的影响。本文主要介绍了美国国家标准与技术研究院(NIST)同步辐射紫外线辐射装置(SURF)所采用的X射线能谱仪器的表征技术。讨论了光谱仪的光谱响应、光谱分辨率、响应线性度以及未来的太阳科学目标。
The Miniature X-ray Solar Spectrometer (MinXSS) are twin 3U CubeSats. The first of the twin CubeSats (MinXSS-1) launched in December 2015 to the International Space Station for deployment in mid-2016. Both MinXSS CubeSats utilize a commercial off the shelf (COTS) X-ray spectrometer from Amptek to measure the solar irradiance from 0.5 to 30 keV with a nominal 0.15 keV FWHM spectral resolution at 5.9 keV, and a LASP-developed X-ray broadband photometer with similar spectral sensitivity. MinXSS design and development has involved over 40 graduate students supervised by professors and professionals at the University of Colorado at Boulder. The majority of previous solar soft X-ray measurements have been either at high spectral resolution with a narrow bandpass or spectrally integrating (broadband) photometers. MinXSS will conduct unique soft X-ray measurements with moderate spectral resolution over a relatively large energy range to study solar active region evolution, solar flares, and the effects of solar soft X-ray emission on Earth’s ionosphere. This paper focuses on the X-ray spectrometer instrument characterization techniques involving radioactive X-ray sources and the National Institute for Standards and Technology (NIST) Synchrotron Ultraviolet Radiation Facility (SURF). Spectrometer spectral response, spectral resolution, response linearity are discussed as well as future solar science objectives.
