摘要:

高能宇宙辐射探测器(HERD)设施计划在中国的空间站上运行,计划于2025年左右开始运行约10年。HERD的主要科学目标是寻找暗物质湮灭产物的信号,精确的宇宙电子/正电子谱和测量高达10 TeV的各向异性,精确的宇宙射线谱和成分测量高达膝能(1 PeV),以及高能$γ$射线监测和勘测。HERD由一个三维立方晶体量热计(CALO)组成,周围环绕着微带硅跟踪器(STK)和闪烁光纤跟踪器(FIT)以及一个塑料闪烁探测器(PSD),用于$γ$射线否决和离子电荷测量。在意大利帕维亚的CNAO(Centro Nazionale Adroterapia Oncologica),用质子和C离子束对由两个SiPM阵列在相对侧读出的闪烁体瓦片组成的PSD原型进行了测试。电荷分辨率的初步结果。

英文摘要:

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.
