论文摘要
Simons天文台（So）是一个基于地面的宇宙微波背景实验，将部署到智利的Atacama沙漠。因此，将超过60,000个过渡边缘传感器（TES）侧强仪将在27 GHz和280 GHz之间观察到，目的是揭示有关宇宙起源和演变的新信息。因此，探测器根据其观察频率进行分组，并将其包装到通用焦平面模块中，每个模块最多包含1720个检测器，这些检测器使用微波鱿鱼多路复用和SLAC微波炉射频射频电子电子（\ SMURF）读出。通过测量TE的复杂阻抗，我们能够访问检测器的许多热电特性，这些特性很难使用其他校准方法来确定，但是由于高样本速率要求，历史上很难一次测量许多探测器的复杂阻抗。在这里，我们提出了一种使用\ smurf \的方法，以同时在一个小时的时间尺度上测量数百个检测器的复杂阻抗。我们将测得的有效热时间常数与用偏置步骤独立估计的那些进行比较。这种新方法开辟了在实验室和站点中使用此表征工具的可能性，以更好地了解SO探测器的全部人群。
The Simons Observatory (SO) is a ground based Cosmic Microwave Background experiment that will be deployed to the Atacama Desert in Chile. SO will field over 60,000 transition edge sensor (TES) bolometers that will observe in six spectral bands between 27 GHz and 280 GHz with the goal of revealing new information about the origin and evolution of the universe. SO detectors are grouped based on their observing frequency and packaged into Universal Focal Plane Modules, each containing up to 1720 detectors which are read out using microwave SQUID multiplexing and the SLAC Microresonator Radio Frequency Electronics (\smurf). By measuring the complex impedance of a TES we are able to access many thermoelectric properties of the detector that are difficult to determine using other calibration methods, however it has been difficult historically to measure complex impedance for many detectors at once due to high sample rate requirements. Here we present a method which uses \smurf\ to measure the complex impedance of hundreds of detectors simultaneously on hour-long timescales. We compare the measured effective thermal time constants to those estimated independently with bias steps. This new method opens up the possibility for using this characterization tool both in labs and at the site to better understand the full population of SO detectors.
