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 $$R{\sim }275$$ R ∼ 275 spectrometer measured using deployment-ready RF hardware and software. We report typical noise equivalent powers through the full device of $$\sim \,3 \times 10^{-16}$$ ∼ 3 × 10 - 16 $$\hbox {W Hz}^{-1/2}$$ W Hz - 1 / 2 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.

部署级 SuperSpec 毫米波片上光谱仪的全阵列噪声性能

SuperSpec 是一种片上滤波器组光谱仪，设计用于毫米波长的宽带中等分辨率光谱，采用 TiN 动态电感检测器。SuperSpec 技术将使适用于高红移线强度映射和多目标光谱仪的大幅面光谱积分场单元成为可能。在之前的结果中，我们已经证明了适用于在优秀毫米波站点进行光子噪声限制的地面观测的单个探测器的噪声性能。在这些程序中，我们展示了一个完整的 $$R{\sim }275$$ R ∼ 275 光谱仪的噪声性能，该光谱仪使用可部署的 RF 硬件和软件进行测量。我们报告了整个器件的典型噪声等效功率 $$\sim \,3 \times 10^{-16}$$ ∼ 3 × 10 - 16 $$\hbox {W Hz}^{-1/2}$ $ W Hz - 1 / 2 在预期的天空载荷下，其中光子噪声占主导地位。基于这些结果，我们计划在 2020 年初向大型毫米波望远镜部署一台六光谱仪演示仪器。
