摘要:

2019年10月,H.E.S.S.实验已经升级了一个新的相机。该相机基于FlashCam设计,该设计是为了将来可能在切伦科夫望远镜阵列(CTA)的中型望远镜中实现而开发的,重点是成本和性能优化以及可靠性。触发和读出系统的全数字化设计使相机能够以高事件率运行,并精确调整和理解触发系统。前端电子器件的新颖设计实现了超过3,000个光电子的动态范围,每个像素只有一个电子读出电路。在这里,我们报告的性能参数的相机在第一年的操作中获得的领域,包括操作稳定性和优化的校准算法。

英文摘要:

In October 2019, the central 28 m telescope of the H.E.S.S. experiment has been upgraded with a new camera. The camera is based on the FlashCam design which has been developed in view of a possible future implementation in the Medium-Sized Telescopes of the Cherenkov Telescope Array (CTA), with emphasis on cost and performance optimization and on reliability. The fully digital design of the trigger and readout system makes it possible to operate the camera at high event rates and to precisely adjust and understand the trigger system. The novel design of the front-end electronics achieves a dynamic range of over 3,000 photoelectrons with only one electronics readout circuit per pixel. Here we report on the performance parameters of the camera obtained during the first year of operation in the field, including operational stability and optimization of calibration algorithms.
