摘要

我们介绍了一种在电热反馈条件下精确监测过渡边缘传感器（TES）环路增益的方法。该测量方法在 ICE DfMux 电子设备上实现，并与数字主动归零（DAN）同时运行。每个过渡边沿传感器使用一个额外的偏置正弦波，不需要任何额外的读出通道。环路增益监视器正在西蒙斯阵列上实施，是即将发射的 LiteBIRD 卫星基线校准策略的组成部分。

Monitoring TES Loop Gain in Frequency Multiplexed Readout

We present a method for precise monitoring of the loop gain of transition edge sensors (TES) under electrothermal feedback. The measurement is implemented on the ICE DfMux electronics and operates simultaneously with Digital Active Nulling (DAN). It uses one additional bias sinusoid per TES and does not require any additional readout channels. The loop gain monitor is being implemented on the Simons Array and is an integral part of the baseline calibration strategy for the upcoming LiteBIRD satellite.
