论文摘要
SuperSPEC是一种芯片过滤器银行光谱仪，设计用于毫米波长的宽带中分辨率光谱仪，采用锡动力电感探测器。 SuperSPEC技术将实现适合高红移线强度映射和多对象光谱仪的大型光谱积分单元。在先前的结果中，我们已经证明了适用于光子噪声有限地面观测值的单个检测器中的噪声性能。在这些程序中，我们介绍了使用Deployment准备就绪的RF硬件和软件测量的完整$ r \ sim 275 $光谱仪的噪声性能。我们通过$ \ sim 3 \ sim 3 \ times 10^{ - 16} \ \ mathrm {w}/\ sqrt {\ mathrm {hz}} $在预期的天空载荷上报告典型的噪声等效功率。基于这些结果，我们计划在2020年初向大毫米望远镜部署六光表示范工具。
SuperSpec is an on-chip filter-bank spectrometer designed for wideband moderate-resolution spectroscopy at millimeter wavelengths, employing TiN kinetic inductance detectors. SuperSpec technology will enable large-format spectroscopic integral field units suitable for high-redshift line intensity mapping and multi-object spectrographs. In previous results we have demonstrated noise performance in individual detectors suitable for photon noise limited ground-based observations at excellent mm-wave sites. In these proceedings we present the noise performance of a full $R\sim 275$ spectrometer measured using deployment-ready RF hardware and software. We report typical noise equivalent powers through the full device of $\sim 3 \times 10^{-16} \ \mathrm{W}/\sqrt{\mathrm{Hz}}$ at expected sky loadings, which are photon noise dominated. Based on these results, we plan to deploy a six-spectrometer demonstration instrument to the Large Millimeter Telescope in early 2020.
