Modelling a Transition-Edge Sensor X-ray Microcalorimeter Linear Array for Compton Profile Measurements and Energy Dispersive Diffraction
摘要：
过渡边缘传感器是一种超导探测器，其基于在超导到正常过渡中的尖锐电阻温度特征提供高能量分辨率。TES X射线微量热计通常被设计并用于光谱应用。在这项工作中，我们提出了一个设计优化的TES X射线微热阵列的高能量散射和衍射测量。特别地，康普顿散射提供关于电子动量分布的信息，而能量色散衍射提供关于致密工程材料的结构信息。康普顿散射和能量色散衍射实验必须在非常硬的X射线状态（~ 100 keV）下进行，这要求探测器中具有高的X射线阻止功率;因此，需要与TES结合的具有大热容量的吸收体。此外，这两种应用都将受益于由平行条带组成的阵列。我们提出了一种设计的TES X射线微量热仪优化这样的应用。特别是，我们的模型的纵向位置依赖性，由于有限的热扩散时间在吸收体。
英文摘要：
Transition-edge sensors are a type of superconducting detector that offers high energy resolution based on their sharp resistance-temperature feature in the superconducting-to-normal transition. TES X-ray microcalorimeters have typically been designed and used for spectroscopic applications. In this work, we present a design optimization for a TES X-ray microcalorimeter array for high-energy scattering and diffraction measurements. In particular, Compton scattering provides information about the electron momentum distribution, while energy dispersive diffraction provides structural information about dense engineering materials. Compton scattering and energy dispersive diffraction experiments must be conducted in the very hard X-ray regime (~ 100 keV), demanding a high X-ray stopping power in the detector; therefore, an absorber with a large heat capacity is needed in conjunction with the TES. In addition, both applications would benefit from an array composed of parallel strips. We present a design for a TES X-ray microcalorimeter optimized for such applications. In particular, we model the longitudinal position dependence due to the finite thermal diffusion time in the absorber.
