Abstract
The High Energy cosmic Radiation Detector (HERD) stands out as one of the most promising projects for space-based direct detection of cosmic rays. It is planned to be installed on the Chinese Space Station in 2027. The core of HERD is a 3D segmented, homogeneous, spherical calorimeter, featuring a total depth of 55X0. Three sub-detectors, namely the scintillating FIbres Tracker, Plastic Scintillation Detector, and Silicon Charge Detector, will enclose five out of six sides. Additionally, a Transition Radiation Detector will be installed on one face for online calibration of TeV energy events. HERD’s innovative design ensures a geometrical acceptance at least 10 times larger than that of any of its predecessors. This enhanced capability will enable the measurement of cosmic ray spectra and composition up to the PeV energy scale, to conduct precision studies in γ-ray astrophysics, to monitor transient events, and indirectly search for dark matter candidates with unprecedented accuracy.
