电压偏置超导过渡边缘传感器的响应性和噪声在很大程度上取决于其热模型的细节，最简单的TES响应理论假设与热浴相连的单个热容。本文推导并讨论了当热模型不是简单的而是由两个或三个相连的热容组成时，过渡边缘传感器的复杂阻抗、响应性和噪声的分析结果。本文还讨论了模型差异的含义。版权所有2012作者本文采用知识共享署名3.0未移植许可协议发布。[http://dx.doi.org/10.1063/1.4759111]
The responsivity and noise of a voltage-biased superconducting transition-edge sensor depends strongly on the details of its thermal model, and the simplest theory for TES response assumes a single heat capacity connected to the heat bath. Here, analytical results are derived and discussed for the complex impedance, the responsivity and the noise of a transition-edge sensor, when the thermal model is not simple but consists of either two or three connected heat capacities. The implications of the differences of the models are discussed, as well. Copyright 2012 Author(s). This article is distributed under a Creative Commons Attribution 3.0 Unported License.
