具有足够的灵敏度来分辨单光子和粒子的能量并结合快速响应时间的探测器正变得越来越重要。我们描述了最近提出的一种传感器的进展情况，我们将其命名为电感超导过渡边缘检测器（ISTED）。我们已经从理论上估计了这种传感器的能量灵敏度，在这种情况下，吸热器被集成在纳米级SQUID的敏感区域内，作为感应读出装置。介绍了在5-8 K温度范围内原型器件的实验表征的最新结果，并描述了旨在实现更小器件尺寸和更低工作温度的正在进行的工作。
Detectors with sufficient sensitivity to resolve the energy of single photons and particles combined with rapid response times are becoming increasingly important. We describe work in progress on a recently-proposed type of sensor, which we have named the Inductive Superconducting Transition Edge Detector (ISTED). We have theoretically estimated the energy sensitivity of such a sensor, in the case where the heat absorber is incorporated within the sensitive area of a nano-scale SQUID which acts as an inductive readout device. Recent results on the experimental characterization of prototype devices in the temperature range 5-8 K are presented, and ongoing work which is intended to achieve smaller device dimensions together with lower operating temperatures is described.
