Abstract

We developed a modular silicon photomultiplier camera to detect Earth-skimming PeV to EeV tau neutrinos with the imaging atmospheric Cherenkov technique. We built two cameras, a 256-pixel camera for the Trinity Demonstrator located on Frisco Peak, Utah, and a 512-pixel camera for the Extreme Universe Observatory on a Super-Pressure Balloon II (EUSO-SPB2) Cherenkov Telescope. The front-end electronics are based on the Multipurpose Integrated Circuit (eMUSIC) Application Specific Integrated Circuits (ASICs), and the camera signals are sampled and digitized with the 100 MS/s and 12-bit ASIC for General Electronics for TPC (AGET) system. Both cameras are liquid-cooled. We detail the camera concept and the results from characterizing the SiPMs, bench testing, and calibrating the two cameras.

三位一体演示器和 EUSO-SPB2 切伦科夫望远镜的照相机和读取器

我们开发了一种模块化硅光电倍增管照相机，利用成像大气切伦科夫技术来探测掠地PeV到EeV的陶中微子。我们制造了两台照相机，一台用于犹他州弗里斯科峰的三位一体演示器（Trinity Demonstrator）的 256 像素照相机，另一台用于超压气球 II（EUSO-SPB2）上的极端宇宙观测站（Extreme Universe Observatory on a Super-Pressure Balloon II）的切伦科夫望远镜（Cherenkov Telescope）的 512 像素照相机。前端电子设备采用多用途集成电路 (eMUSIC) 专用集成电路 (ASIC)，照相机信号采用 100 MS/s 和 12 位 AGET 通用电子系统专用集成电路 (ASIC)进行采样和数字化。两台照相机都是液冷的。我们详细介绍了相机的概念以及 SiPM 的特性、台架测试和校准两台相机的结果。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
