长E-2卫星软X射线探测器在轨定标
On-orbit calibration of soft X-ray detector on Chang'E-2 satellite
摘要:
X射线谱仪是嫦娥二号卫星的有效载荷之一。软X射线探测器是X射线谱仪中的一种装置,用于探测月球表面0.5- 10 keV范围内的主要造岩元素。本文利用弱Fe ~(55)源进行了能量线性度和能量分辨率的标定,考虑了温度和时间的影响,误差不大。校正后的总不确定度估计在5%以内。
英文摘要:
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.
