Abstract
En 中文
The High Energy cosmic-Radiation Detection (HERD) facility is planned to be operational on China Space Station (CSS) starting from 2028, with a projected duration of approximately 10 years. With the high-accuracy silicon charge detector (SCD) and silicon tracker (STK) forming a compact structure, HERD is capable to provide charge and direction measurement from the trajectory measurement of charged cosmic-rays. A cellular automata-based track reconstruction algorithm is developed and validated on HERD Monte Carlo simulation data. The efficiency of this algorithm reaches > 93% for 100 GeV proton, helium and carbon events while keeping low fake rate < 2%.
