Introduction to the High Energy cosmic-Radiation Detection (HERD) Facility onboard China’s Future Space Station

Abstract: PoS(ICRC2017)1077The High Energy cosmic-Radiation Detection (HERD) facility is one of several space astronomy payloads onboard China's Space Station, which is planned for operation starting around 2025 for about 10 years. The main scientific objectives of HERD are searching for signals of dark matter annihilation products, precise cosmic electron (plus positron) spectrum and anisotropy measurements up to 10 TeV, precise cosmic ray spectrum and composition measurements up to the knee energy, and high energy gam… Show more

“…Despite the various successful missions for measurement of CRs in space, many open issues limit our understanding of the origin, acceleration, and propagation mechanisms of CRs. Proposals for instruments for the measurement of high-energy CRs in the TeV-PeV energy range include the all-calorimetric HERD instrument onboard the Chinese Space Station [31] and the spectrometric instrument AMS-100 proposed for operations in Earth-Sun Lagrange Point L2 [32]. Figure 1 reports a summary of the most relevant operating and planned instruments for measurement of high-energy CRs in space.…”

“…This concept well fits with the geometry of the ALADInO spectrometer. In addition, its development will benefit from the experience gained in the design, preliminary tests, and possible future commissioning of the HERD calorimeter [31,162].…”

“…It relies on the fact that most cosmic-ray detectors feature an electromagnetic calorimeter below the main tracking device, with the main purpose of measuring the particle energy and discriminating electrons and protons by means of topological shower analysis. Indeed, the effort towards the high-energy frontier in space (sub-TeV for gamma rays, multi-TeV for electrons and PeV for hadrons) is being pursued by running [4,5] and future [6] experiments mainly with deep, homogenous electromagnetic calorimeters with scintillating crystals. When a photon hits the calorimeter it generates an electromagnetic shower, whose axis preserves the information about its direction.…”

“…To quantitatively assess the expected performance of the tracking calorimeter proposed in the previous section, a FLUKA [10,11] Monte Carlo simulation has been set up. The simulated detector is modeled adopting some of the design choices of the future HERD calorimeter [6] (which in turn follows in many aspects the CaloCube design described in section 3): the thin and cubic crystals are made of Lutetium Yttrium Orthosilicate (Lu 2 SiO 5 ), commonly known as LYSO, and the cubes have side 3 cm while the thin scintillators are 1.5 cm (i.e. half-cube) thick.…”

“…[2]. LYSO crystals are also proposed to construct a total absorption calorimeter for the COMET experiment at KEK [3], and a 3D calorimeter for the proposed HERD experiment in space [4]. Undoped CsI crystals are used to construct a calorimeter for the Mu2e experiment at Fermilab [5].…”
