标题： On-orbit calibration of soft X-ray detector on Chang'E-2 satellite

摘要： X射线光谱仪是嫦娥二号卫星上的一个有效载荷。 软X射线探测器是X射线光谱仪上的一个装置，设计用于检测月球表面0.5-10keV范围内的主要造岩元素。 本文使用弱铁55源进行能量线性和能量分辨率的校准，而温度和时间的影响被认为不会带来太大误差。 校正后总不确定度估计在5%以内。 显示英文摘要

摘要： X-ray spectrometer is one of the satellite payloads on Chang'E-2 satellite. The soft X-ray detector is one of the device on X-ray spectrometer which is designed to detect the major rock-forming elements within 0.5-10keV range on lunar surface. In this paper, energy linearity and energy resolution calibration is done using a weak Fe55 source, while temperature and time effect is considered not take big error. The total uncertainty is estimated to be within 5% after correction.
