我们报道了一种位置敏感的过渡边缘传感器(POST)的最新设计和实验结果。该职位的动机是希望在不增加读出通道数量的情况下实现更大的视场。柱子由一维的X射线吸收器阵列组成，每一端都连接到过渡边缘传感器(TES)。通过比较两个TESS之间的脉冲来实现位置区分，并且从两个信号的总和推断X射线能量。优化这种器件涉及研究可用参数空间，该参数空间包括诸如热容量和导热系数的器件属性以及TES读出电路参数。我们给出了不同运行模式的结果，以及对能量分辨率、吞吐量和位置差异化的影响。还介绍了为研究员额特有的饱和效应而开发的非线性模型的结果和影响。
We report the latest design and experimental results for a Position-Sensitive Transition-Edge Sensor (PoST). The PoST is motivated by the desire to achieve a larger field-of-view without increasing the number of readout channels. A PoST consists of a one-dimensional array of X-ray absorbers connected on each end to a Transition Edge Sensor (TES). Position differentiation is achieved through a comparison of pulses between the two TESs and X-ray energy is inferred from a sum of the two signals. Optimizing such a device involves studying the available parameter space which includes device properties such as heat capacity and thermal conductivity as well as TES read-out circuitry parameters. We present results for different regimes of operation and the effects on energy resolution, throughput, and position differentiation. Results and implications from a non-linear model developed to study the saturation effects unique to PoSTs are also presented.
