论文摘要
预计弗雷德Young亚毫米望远镜（FYST）上的Prime-Cam仪器将是迄今为止最大的毫米和亚毫米敏感动力电感探测器的部署。为了有效地读取这些数组，已经设计了微波频率多路复用的读数，可在芯片上的Xilinx射频系统（RFSOC）上运行。 RFSOC在上一代读取系统上大大改善了大小，重量，功率，成本和带宽的每个类别。我们描述了一个基线固件设计，该设计可以读取四个独立的RF网络，每个网络具有500 MHz的带宽和1000个探测器的〜30W。总体读取体系结构是硬件，gateware/stoneware，startware，软件和网络设计的组合。读数的要求是由7模块Prime-Cam仪器的850 GHz仪器模块驱动的。这些要求以及导致关键设计选择的其他约束。提出了系统相位噪声和动态范围的初步测量。
The Prime-Cam instrument on the Fred Young Submillimeter Telescope (FYST) is expected to be the largest deployment of millimeter and submillimeter sensitive kinetic inductance detectors to date. To read out these arrays efficiently, a microwave frequency multiplexed readout has been designed to run on the Xilinx Radio Frequency System on a Chip (RFSoC). The RFSoC has dramatically improved every category of size, weight, power, cost, and bandwidth over the previous generation readout systems. We describe a baseline firmware design which can read out four independent RF networks each with 500 MHz of bandwidth and 1000 detectors for ~30 W. The overall readout architecture is a combination of hardware, gateware/firmware, software, and network design. The requirements of the readout are driven by the 850 GHz instrument module of the 7-module Prime-Cam instrument. These requirements along with other constraints which have led to critical design choices are highlighted. Preliminary measurements of the system phase noise and dynamic range are presented.
