摘要

我们描述了超导阵列的可重构频率复用读出系统的发展。该系统是我们为许多气球载和地面仪器(包括BLAST-TNG, OLIMPO, MUSCAT, Superspec和TolTEC)开发的基于ROACH2的读出系统的升级版。具体来说，我们的开发目标是RFSoC ZCU111评估板，其尺寸，重量，功率和瞬时带宽使其成为未来气球载或天基天文仪器的有吸引力的候选者。新的读出系统的应用主要集中在:频率复用超导纳米线单光子探测器、动态电感探测器、过渡边缘传感器和量子电容探测器。我们将讨论驱动一般固件架构的重叠读出需求。还将介绍使用不同探测器技术的新读出系统的初步测量结果。

On the development of a reconfigurable readout for superconducting arrays

We describe the development of a reconfigurable frequency multiplexed readout system for superconducting arrays. This system is an upgrade to the ROACH2 based readout system we have developed for a number of balloon-borne and ground-based instruments including BLAST-TNG, OLIMPO, MUSCAT, Superspec and TolTEC. Specifically our development has targeted the RFSoC ZCU111 evaluation board of which the size, weight, power, and instantaneous bandwidth have made it an attractive candidate for future balloon-borne or space-based astronomical instruments. Applications for the new readout system focus primarily on: frequency multiplexed superconducting nanowires single-photon detectors, Kinetic inductance detectors, Transition Edge Sensors, and Quantum Capacitance detectors. We will discuss the overlapping readout requirements that drive the general firmware architecture. Preliminary measurements with the new readout system using different detector technologies will also be presented.
