Understanding the magnetic field sensitivity of transition edge sensors (TESs) is vital in optimising the configuration of any magnetic shielding as well as the design of the TESs themselves. An experimental system has been developed to enable the investigation of the applied magnetic field direction on TES behaviour, and the first results from this system are presented. In addition, measurements of the effect of applied magnetic field magnitude on both supercurrent and bias current are presented. The extent to which the current theoretical framework can explain the results is assessed and finally, the impact of this work on the design of TESs and the design of magnetic shielding is discussed.

过渡边缘传感器的磁场灵敏度


了解过渡边缘传感器 (TES) 的磁场灵敏度对于优化任何磁屏蔽的配置以及 TES 本身的设计至关重要。我们开发了一个实验系统来研究外加磁场方向对 TES 行为的影响，并提出了该系统的第一个结果。此外，还测量了施加的磁场强度对超电流和偏置电流的影响。评估了当前理论框架可以在多大程度上解释结果，最后讨论了这项工作对 TES 设计和磁屏蔽设计的影响。
