我们正在开发频分复用（FDM）读出系统，旨在实现DIOS使命的400像素过渡边缘传感器（TES）微量热计阵列，以及未来空间任务（如ATHENA使命）的超过一千个TES的大格式阵列。所开发的系统包括低功率超导量子干涉仪（SQUID），数字FDM电子学，模拟前端的SQUID和数字电子学的桥梁。利用研制的读出系统，我们进行了TES读出实验，并成功地与单级低温装置多路复用四TES信号。我们在实验过程中遇到了两个问题：过量噪声和串扰。简要概述了开发的系统和TES复用读出实验的细节，结果和问题进行了讨论。
We are developing the frequency-division multiplexing (FDM) readout system aimed to realize the 400-pixel transition edge sensor (TES) microcalorimeter array for the DIOS mission as well as large-format arrays with more than a thousand of TES for future space missions such as the ATHENA mission. The developed system consists of the low-power superconducting quantum interference device (SQUID), the digital FDM electronics, and the analog front-end to bridge the SQUID and the digital electronics. Using the developed readout system, we performed a TES readout experiment and succeeded to multiplex four TES signals with the single-staged cryogenic setup. We have experienced two issues during the experiment: an excess noise and crosstalk. The brief overview of the developed system and the details, results, and issues of the TES multiplexing readout experiment is discussed.
