Abstract
The High Energy cosmic-Radiation Detection (HERD) facility is a future space experiment which is designed for the direct
measurement of cosmic-rays (CR). The instrument will be installed aboard the China’s Space Station around 2027 and is based on a
homogeneous, deep, 3D segmented calorimeter. The calorimeter is surrounded by scintillating fiber trackers, anti-coincidence scintillators, silicon charge detectors, and a transition radiation detector. The HERD instrument is designed to feature a very large acceptance, thus allowing the extension of current measurements up to much higher energies. e.g. the few PeV region in the case of light nuclei, depending on their actual flux.. Fundamental progress in our understanding of propagation and acceleration of CR inside the Galaxy will be achieved by measuring the flux of protons and nuclei above hundreds of TeV per nucleon. By exploring the electron flux in the multi-TeV region, it will be possible to search for the signature of dark matter and nearby astrophysical sources. Finally, thanks to the large field of view, the experiment will also monitor the gamma-ray sky from a few hundred of MeV up to 1 TeV. In this paper a review of the current status of the experiment is presented.
