Description
The High Energy cosmic-Radiation Detection (HERD) facility is one of the Cosmic Lighthouse Program onboard China’s Space Station. HERD is designed for the direct measurement of high-energy electrons, gamma-rays and in general all the cosmic ray nuclear species. Is planned for operation starting around 2027 for about 10 years.
HERD is composed of five sub-detectors: an homogeneous, deep, 3D segmented calorimeter (CALO), a FIber Tracker (FIT), a Plastic Scintillation Detector (PSD), a Silicon Charge Detector (SCD), and a Transition Radiation Detector (TRD). Thanks to its large acceptance and sensitivity, HERD will be able to extend the current measurements up to much higher energies.In this contribution, a preliminary study of the performance of Silicon Charge Detector (SCD) prototype, with the results from HERD prototype beam test at CERN SPS in 2022, will be presented. We’ll review the main evaluated performances, such as the Signal-to-Noise ratio, the charge resolution, and the spatial resolution.
