Abstract
The HERD (High Energy cosmic-Radiation Detection facility) experiment is a future experiment for the direct detection of cosmic rays, that will be installed on the Chinese space station in 2027. It is based on a calorimeter with an innovative geometry: it is indeed composed of about 7500 LYSO cubic scintillating crystals assembled in a spheroidal shape. Thanks to this specific geometry and to the equipment of sub-detectors on five sides around the calorimeter, HERD will be capable to detect particles entering from five sides. This will lead to an increment in the geometric factor of more than one order of magnitude compared to the current in-orbit calorimetric experiments. Thanks to its enormous geometric factor HERD will extend cosmic-ray direct measurements more than one order of magnitude in energy. Indeed, it will directly detect for the first time the proton and helium knee. In addition, it will measure electron+positron flux up to tens of TeV looking for local sources of high energy leptons and for indirect signals of dark matter. Finally, HERD will also be a gamma-ray observatory. It is designed to be a new instrument for multi-messenger astronomy, study cosmic-ray acceleration sources and look for indirect signals of dark matter. In this article we will introduce the HERD experiment with its scientific objectives and its detector.
