我们已经完成了一个探空火箭的有效载荷，将使用一个36元阵列的微量热仪，以获得高分辨率的光谱的扩散X射线背景之间的0.1和1千电子伏。这个实验只使用机械准直的入射X射线，但低温恒温器和探测器组件已被设计成放置在一个圆锥形箔成像镜的焦点，这将用于后续的飞行做空间分辨光谱超新星遗迹和其他扩展对象。探测器系统是一个单片阵列的硅量热计与离子注入温度计和碲化汞X射线吸收剂。在60 mK下工作的1 mm2像素实现约8 eV FWHM的分辨率。
We have completed a sounding rocket payload that will use a 36 element array of microcalorimeters to obtain a high-resolution spectrum of the diffuse X-ray background between 0.1 and 1 keV. This experiment uses only mechanical collimation of the incoming X-rays, but the cryostat and detector assembly have been designed to be placed at the focus of a conical foil imaging mirror which will be employed on subsequent flights to do spatially resolved spectroscopy of supernova remnants and other extended objects. The detector system is a monolithic array of silicon calorimeters with ion-implanted thermometers and HgTe X-ray absorbers. The 1 mm2pixels achieve a resolution of about 8 eV FWHM operating at 60 mK.
