我们报告的进展，到目前为止，在美国宇航局戈达德航天飞行中心对发展阵列的X射线微量热仪作为候选人的高分辨率X射线光谱仪的星座-X使命。在目前考虑的设计概念中，微量热计包括（i）用于阻止和热化入射X射线的Bi/Cu多层吸收器，（ii）具有溅射Nb引线的电子束蒸发的Mo/Au邻近双层，用于感测所产生的温度升高，以及（iii）氮化硅膜，以提供到散热温度的弱热连接，使得量热计可以返回到其平衡温度。制造细节和初步结果的报告。
We report on progress made so far at NASA Goddard Space Flight Center towards the development of arrays of X-ray microcalorimeters as candidates for the high-resolution X-ray spectrometer on the Constellation-X mission. In the design concept presently under consideration, the microcalorimeter consists of (i) a Bi/Cu multilayer absorber for stopping and thermalizing the incident X-rays, (ii) an e-beam evaporated Mo/Au proximity bilayer with sputtered Nb leads for sensing the resultant temperature rise, and (iii) a silicon nitride membrane to provide a weak thermal link to the sink temperature so that the calorimeter can return to its equilibrium temperature. Fabrication details and preliminary results are reported.
