本文介绍NectarCAM相机用于CTAO中型望远镜,其时序系统经暗室测试,可降噪、改善图像清洗并区分伽马与宇宙射线,支持立体观测。

摘要:

NectarCAM是一种切伦科夫相机,将安装在切伦科夫望远镜阵列天文台(CTAO)北阵列的中型望远镜上。它由265个模块组成,每个模块包含7个光电倍增管、一个前端板和一个用于数据收集的相机触发系统。首个NectarCAM单元目前正在法国CEA巴黎-萨克雷进行集成。一旦安装在CTAO的北部站点,NectarCAM的时序能力将对减少图像中的噪声、改善图像清洗以及区分伽马射线光子和宇宙射线背景至关重要。此外,它将能够与邻近望远镜进行符合识别,用于立体观测。NectarCAM的时序系统已在暗室中使用各种光源进行了测试。测试结果,包括相对于激光源的触发到达的时序精度和准确度,以及单个和多个像素信号的时序,将被展示。

英文摘要:

NectarCAM is a Cherenkov camera that will be installed on Medium-Sized Telescopes of the northern array of the Cherenkov Telescope Array Observatory (CTAO). It is composed of 265 modules, each of which includes 7 photo-multiplier tubes, a Front-End Board and a camera trigger system for data collection. The first NectarCAM unit is currently being integrated at CEA Paris-Saclay in France. Once installed at the CTAO's northern site, the NectarCAM's timing abilities will be crucial for reducing noise in images, improving image cleaning, and distinguishing between gamma-ray photons and cosmic-ray background. Additionally, it will enable coincidence identification with neighboring telescopes for stereoscopic observations. The timing system of NectarCAM has been tested in a dark room with various light sources. The results of the tests, including timing precision and accuracy of the trigger arrival relative to a laser source, and the timing of individual and multiple pixel signals, will be presented.
