论文摘要
计划在中国的空间站上进行高能宇宙辐射探测器(HERD)设施,计划在2025年左右开始运营大约10年。牛群的主要科学目标是寻找暗物质歼灭产品的信号,精确的宇宙电子/正电子光谱以及高达10 TEV的各向异性的测量,精确的宇宙射线光谱和膝盖能量(1 PEV)以及高能量$ $ um $ um-γ$ - 雷液监视和调查。畜群由一个3D立方晶体量热计(CARO)组成,周围是微带硅跟踪器(STK)和闪烁的纤维追踪器(fit)和塑料闪烁体检测器(PSD),以$γ$ - 射线否决和离子电荷电荷测量。在帕维亚(意大利)的CNAO(Centro Nazionale Adroterapia oncologica)的CNAO(意大利)的CNAO(Centro Nazionale Adroterapia oncologica)上,已用质子和c离子束在相对侧面由两个尖锐的sipms组成的PSD原型进行了测试。提出了电荷分辨率的初步结果。
The High Energy cosmic-Radiation Detector (HERD) facility is planned to go onboard China's Space Station, planned to be operational starting in around 2025 for about 10 years. The main scientific objectives of HERD are the search for signals of dark matter annihilation products, precise cosmic electron/positron spectrum and measurements of anisotropy up to 10 TeV, precise cosmic ray spectrum and composition measurements up to the knee energy (1 PeV), and high energy $γ$-ray monitoring and survey. HERD consists of a 3D cubic crystals calorimeter (CALO) surrounded by microstrip silicon trackers (STKs) and scintillating fiber trackers (FIT) and by a Plastic Scintillator Detector (PSD) for $γ$-ray veto and ion charge measurement. A PSD prototype consisting of a scintillator tile readout by two arrays of SiPMs on opposite sides has been tested with proton and C ion beam at the CNAO (Centro Nazionale Adroterapia Oncologica) in Pavia, (Italy). Preliminary results on charge resolution are presented.
