用于ccat prime项目的Fred Young亚毫米望远镜上的Prime-Cam接收器旨在通过敏感的宽带、偏振和光谱测量来解决重要的天体物理和宇宙学问题。正在开发的主要频段包括280、350和850 GHz用于极化敏感宽带信道,210-420 GHz用于光谱仪。微波动力学电感探测器(MKIDs)是探测器技术的自然选择,因为在这些高频率下,大格式阵列需要简单的多路读出。我们在这里介绍了馈角耦合280 GHz极化MKID阵列的初步实验室表征,并概述了后续MKID阵列的计划和测试平台的开发。
The Prime-Cam receiver on the Fred Young Submillimeter Telescope for the CCAT-prime project aims to address important astrophysical and cosmological questions with sensitive broadband, polarimetric, and spectroscopic measurements. The primary frequency bands in development include 280, 350, and 850 GHz for the polarization-sensitive broadband channels and 210–420 GHz for the spectrometers. Microwave kinetic inductance detectors (MKIDs) are a natural choice of detector technology for the simplicity in multiplexed readout needed for large format arrays at these high frequencies. We present here the initial laboratory characterization of the feedhorn-coupled 280 GHz polarimetric MKID array and outline the plans for the subsequent MKID arrays and the development of the testbed to characterize them.
