我们提出了RF-ICE,微波动力学电感探测器(MKID),优化毫米波长望远镜上使用的一种新的读出平台。RF-ICE系统将ICE扩展到一个新的操作领域,ICE是一个多功能的成熟信号处理平台,目前在世界各地的望远镜上使用,MKID偏置千兆赫载波。该系统将基于FPGA的ICE主板与射频数字化子板耦合,实现0至6 GHz的直接数字合成,而无需外部混频。该系统操作两个独立的读出模块,每个模块具有1024个频率复用读出通道,间隔500 MHz的载波带宽。该系统正在积极开发中,正在使用原型探测器晶片进行操作,并将用于即将进行的SPT-SLIM和SPT-3G+实验。
We present RF-ICE, a novel readout platform for microwave kinetic inductance detectors (MKIDs), optimized for use on millimeter-wavelength telescopes. The RF-ICE system extends ICE, a versatile, mature signal processing platform currently in use on telescopes around the world, into a new operational domain with MKIDs biased with gigahertz carriers. The system couples the FPGA-based ICE motherboard with a radio-frequency digitization daughterboard to enable direct digital synthesis from 0 to 6 GHz without the need for external mixing. The system operates two independent readout modules, each with 1024 frequency-multiplexed readout channels spaced across 500 MHz of carrier bandwidth. The system, which is under active development, is in operation with prototype detector wafers and will be deployed for the upcoming SPT-SLIM and SPT-3G+ experiments.
