摘要：
过渡边缘传感器（TESs）能够进行高度精确的单粒子能量测量。TESs已被广泛应用于各种光子探测场景，尤其是在天文学领域，但对其作为电子量热计的能力却鲜有考虑。现有的电子能谱仪需要电子滤波光学器件来实现能量分辨，但这一步骤会丢弃进入仪器的绝大多数电子。TESs无需此类能量滤波，这意味着它们可以在测量速率上提供数量级的提升。为了研究TESs在电子能谱学中的能力，设计了一个模拟流程。该流程允许将模拟实验的结果与入射束的实际能谱进行比较，从而可以研究测量精度和效率。利用Fisher信息，还计算了模拟探测器的能量分辨率，从而可以将探测器的固有局限与所使用的特定数据分析方法区分开来。该模拟平台已被用于将TESs的性能与现有的X射线光电子能谱（XPS）分析仪进行比较。对于高精度测量，TESs无法匹敌XPS分析仪的能量分辨率，但在高计数率应用中具有相当或更好的分辨率。一个由10个响应时间为120微秒的TESs组成的阵列可以匹配典型XPS分析仪的测量速率，并且通过增加阵列规模，在不牺牲能量分辨率的情况下，还有显著的改进空间。
英文摘要：
Transition-edge sensors (TESs) are capable of highly accurate single particle energy measurement. TESs have been used for a wide range of photon detection applications, particularly in astronomy, but very little consideration has been given to their capabilities as electron calorimeters. Existing electron spectrometers require electron filtering optics to achieve energy discrimination, but this step discards the vast majority of electrons entering the instrument. TESs require no such energy filtering, meaning they could provide orders of magnitude improvement in measurement rate. To investigate the capabilities of TESs in electron spectroscopy, a simulation pipeline has been devised. The pipeline allows the results of a simulated experiment to be compared with the actual spectrum of the incident beam, thereby allowing measurement accuracy and efficiency to be studied. Using Fisher information, the energy resolution of the simulated detectors was also calculated, allowing the intrinsic limitations of the detector to be separated from the specific data analysis method used. The simulation platform has been used to compare the performance of TESs with existing X-ray photoelectron spectroscopy (XPS) analysers. TESs cannot match the energy resolution of XPS analysers for high-precision measurements but have comparable or better resolutions for high count rate applications. The measurement rate of a typical XPS analyser can be matched by an array of 10 TESs with 120 microsecond response times and there is significant scope for improvement, without compromising energy resolution, by increasing array size.
