论文摘要

碳CII线路的碳CII线（协奏曲）是一个低分辨率光谱仪，具有18.6 Arcmin的瞬时视野，在130-310 GHz透明的大气窗口中运行。它安装在海拔5100 m的12米Atacama Pathfinder实验（APEX）望远镜上。傅立叶变换光谱仪（FTS）包含两个主持4304个动力电感检测器的焦平面。 FTS干涉模式是在不断扫描天空的同时即时记录的。协奏曲的目标之一是通过观察未解决的星系的综合发射来表征宇宙的大规模结构。该方法是一种创新技术，称为线强度映射。在本文中，我们描述了协奏乐器，FTS Beamsplitter振动的影响以及协奏曲主调查的状态。

CarbON CII line in post-rEionization and ReionizaTiOn (CONCERTO) is a low-resolution spectrometer with an instantaneous field-of-view of 18.6 arcmin, operating in the 130-310 GHz transparent atmospheric window. It is installed on the 12-meter Atacama Pathfinder Experiment (APEX) telescope at 5100 m above sea level. The Fourier transform spectrometer (FTS) contains two focal planes hosting a total of 4304 kinetic inductance detectors. The FTS interferometric pattern is recorded on the fly while continuously scanning the sky. One of the goals of CONCERTO is to characterize the large-scale structure of the Universe by observing the integrated emission from unresolved galaxies. This methodology is an innovative technique and is called line intensity mapping. In this paper, we describe the CONCERTO instrument, the effect of the vibration of the FTS beamsplitter, and the status of the CONCERTO main survey.
