论文摘要
我们介绍了实验室中空间绘制动力学敏感探测器（KID）阵列的发光二极管（LED）模块的设计和测量性能。我们的新方法使用的多路复用方案只需要七根电线来控制480个红色LED，并且可以在不添加任何其他电线的情况下扩大LED的数量。这种多路复用方法依赖于活跃的表面固定成分，该组件可以在低温温度下降至10 k的低温测试。液氮中的低温测试和我们的低温恒温器内部表明，多路复用器电路分别在77和10 K下工作。此处介绍的LED模块是针对我们的毫米波检测器模块量身定制的，但是该方法可以与其他基于儿童的探测器系统一起使用。
We present the design and measured performance of a light emitting diode (LED) module for spatially mapping kinetic inductance detector (KID) arrays in the laboratory. Our novel approach uses a multiplexing scheme that only requires seven wires to control 480 red LEDs, and the number of LEDs can be scaled up without adding any additional wires. This multiplexing approach relies on active surface mount components that can operate at cryogenic temperatures down to 10 K. Cryogenic tests in liquid nitrogen and inside our cryostat demonstrate that the multiplexer circuit works at 77 and 10 K, respectively. The LED module presented here is tailored for our millimeter-wave detector modules, but the approach could be adapted for use with other KID-based detector systems.
