我们开发了多通道电子器件 (MCE)，与 NIST 开发的时域多路复用器配合使用，以控制和读取来自超导过渡边缘传感器 (TES) 的大型测辐射热计阵列的信号。这些电子器件是作为亚毫米通用测辐射热计阵列 2 (SCUBA2) 相机的一部分而开发的，但现在已用于其他几种仪器中。与早期版本相比，这些电子器件的主要优点是它们是多通道、完全可编程、适合远程操作并提供干净的几何形状，在低温恒温器和电子器件底盘形成的法拉第笼之外没有电缆。MCE 用于自主确定 TES 和超导量子干涉器件 (SQUID) 放大器的最佳工作点。在观察期间，MCE 执行运行的 PID 伺服，并向每个第一级 SQUID 施加必要的反馈信号，以保持系统处于最佳增益的线性状态。来自 ∼1000 像素阵列的反馈和错误信号可以高达 2 kHz 的速度写入硬盘。
We have developed multi-channel electronics (MCE) which work in concert with time-domain multiplexors developed at NIST, to control and read signals from large format bolometer arrays of superconducting transition edge sensors (TESs). These electronics were developed as part of the Submillimeter Common-User Bolometer Array-2 (SCUBA2 ) camera, but are now used in several other instruments. The main advantages of these electronics compared to earlier versions is that they are multi-channel, fully programmable, suited for remote operations and provide a clean geometry, with no electrical cabling outside of the Faraday cage formed by the cryostat and the electronics chassis.The MCE is used to determine the optimal operating points for the TES and the superconducting quantum interference device (SQUID) amplifiers autonomously. During observation, the MCE execute a running PID-servo and apply to each first stage SQUID a feedback signal necessary to keep the system in a linear regime at optimal gain. The feedback and error signals from a ∼1000-pixel array can be written to hard drive at up to 2 kHz.
