AI总结:

本文总结了NectarCAM在时间分辨率和电荷分辨率方面的性能,以及最新实施的校准技术,同时介绍了NectarCAM的当前状态和计划,预计2026年夏季首台生产型号将完成并用于CTAO的MST路径探测器。

摘要:

NectarCAM是一种设计用于探测80 GeV至50 TeV能量范围内的伽马射线的切连科夫相机。它将为切连科夫望远镜阵列天文台的九台中型望远镜(MSTs)提供装备。NectarCAM由分布在265个模块上的1855个像素组成。每个像素由一个光电倍增管连接到一个NECTAr3芯片。该NECTAr3芯片包含一个12位数字转换器,具有GHz采样率,典型读出死时间约为0.7 μs。在这些报告中,我们强调了NectarCAM在时间和电荷分辨率方面的性能。我们还介绍了最近为相机实施的最新校准技术。最后,我们简要介绍了NectarCAM的当前状态和计划;第一台生产线NectarCAM预计将在2026年夏季完成并准备发货,并计划用于CTAO的MST路径探测器之一。

英文摘要:

NectarCAM is a Cherenkov camera designed to detect gamma rays with energies between 80 GeV and 50 TeV. It will equip nine medium-sized telescopes (MSTs) of the Cherenkov Telescope Array Observatory. NectarCAM consists of 1855 pixels distributed over 265 modules. Each pixel consists of a photomultiplier tube that is connected to a NECTAr3 chip. This NECTAr3 chip contains a 12-bit digitizer with a GHz sampling rate, and has a typical readout deadtime of ${\sim}0.7$ $μ$s. In these proceedings, we highlight the performance of the NectarCAM in terms of time resolution and charge resolution. We also present the latest calibration techniques that were recently implemented for the camera. Finally, we briefly present the current status and plans of the NectarCAM production; the first production-line NectarCAM will be ready for shipment by Summer 2026, and it is planned to equip one of the MST pathfinders of CTAO.
