论文摘要
在2030年代初，ESAS New X射线天文台（Athena）计划推出。它将携带两种主要仪器，其中一种是X射线积分单元（X-IFU），一个X射线成像光谱仪，由数千个过渡边缘传感器（TESS）组成，提议的能量分辨率为2.5 eV，用于2.5 eV，用于光子能量，最高为7 keV。在SRON，我们基于Ti/Au Bilayers的过渡温度低于100 mk的备用TES阵列。在这项贡献中，我们将概述这些最先进的探测器的属性和功能。多年来，我们已经制造并研究了大量具有各种几何形状的探测器，从而使我们对如何精确控制检测器的性质有很好的了解。我们能够准确地改变最重要的检测器特性，例如正常电阻，导热和临界温度。这使我们能够很好地调整探测器以满足各种应用的需求。这些探测器显示出5.9 keV X射线的出色能量分辨率低于1.8 eV。通过调整设备的属性，可以使用AC和DC偏置最佳地匹配各种读出方案。下一步是将TES阵列的大小从当前的千金阵列增加到X-IFU的全尺寸阵列。
In the early 2030s, ESAs new X-ray observatory, Athena, is scheduled to be launched. It will carry two main instruments, one of which is the X-ray Integral Field Unit (X-IFU), an X-ray imaging spectrometer, which will consist of an array of several thousand transition-edge sensors (TESs) with a proposed energy resolution of 2.5 eV for photon energies up to 7 keV. At SRON we develop the backup TES array based on Ti/Au bilayers with a transition temperature just below 100 mK. In this contribution we will give a broad overview of the properties and capabilities of these state-of-the-art detectors. Over the years we have fabricated and studied a large number of detectors with various geometries, providing us with a good understanding of how to precisely control the properties of our detectors. We are able to accurately vary the most important detector properties, such as the normal resistance, thermal conductance and critical temperature. This allows us to finely tune our detectors to meet the demands of various applications. The detectors have demonstrated excellent energy resolutions of below 1.8 eV for 5.9 keV X-rays. By tuning the properties of the devices, they can be optimally matched to various read-out schemes using both AC and DC biasing. The next step is to increase the size of our TES arrays from our current kilo-pixel arrays towards the full-sized array for X-IFU.
