摘要:

研制了一种用于毫米波天文学的动态电感探测器(KIDS)阵列实时监测的数字频率复用电子学样机。它只需要2个同轴电缆的仪器大阵列。为此,产生频率的激励梳并通过检测器馈送。直接频率合成和数据采集在很大程度上依赖于一个大的FPGA使用并行和流水线处理。该原型可以在125 MHz的带宽上测量128个谐振器(像素)。本文介绍了所选择的技术方案,所使用的算法和所获得的结果。

英文摘要:

A prototype of digital frequency multiplexing electronics allowing the real time monitoring of kinetic inductance detector (KIDs) arrays for mm-wave astronomy has been developed. It requires only 2 coaxial cables for instrumenting a large array. For that, an excitation comb of frequencies is generated and fed through the detector. The direct frequency synthesis and the data acquisition relies heavily on a large FPGA using parallelized and pipelined processing. The prototype can instrument 128 resonators (pixels) over a bandwidth of 125 MHz. This paper describes the technical solution chosen, the algorithm used and the results obtained.
