The CALorimetric Electron Telescope (CALET) is a high-energy multi-detector instrument collecting astroparticle physics science data on the International Space Station (ISS) since October 2015 with excellent and continuous performance. Developed and operated by JAXA in collaboration with ASI and NASA, it investigates on the possible presence of nearby sources of high-energy electrons, while...
DAMPE (DArk Matter Particle Explorer) is calorimetric detector providing unprecedented acceptance and precession for direct detection of cosmic rays in space
in the TeV - 100 TeV range. It has been in excellent operating condition since its successful launch in December 2015. A large amount
a large amount of cosmic ray data has been collected and significant results have been published on...
AMS-02 is a large acceptance magnetic spectrometer operating on the International Space Station since 19th May 2011. AMS-02 has provided precise measurements of the fluxes of individual cosmic ray species in the rigidity range from 1 GV to several TV. The excellent identification capabilities and accurate energy determination are based on a redundant, highly reliable, and flexible design that...
The Alpha Magnetic Spectrometer (AMS) is a particle physics experiment on board the International Space Station (ISS) designed to accurately measure the principal and the rarest Cosmic Rays components in the rigidity range from 1 GV to several TV.
Following a long period of construction and testing, AMS was launched to the ISS and installed on May 19, 2011, and since then collects data and...
The GAPS experiment is designed to conduct a dark matter search by measuring low-energy cosmic-ray antinuclei with a novel detection approach. For the case of antiprotons, a high-statistics measurement in the unexplored low-energy range will be conducted. In contrast, not a single cosmic antideuteron has been detected by any experiment thus far. However, well-motivated theories beyond the...
The search for low energy anti-deuterons in cosmic rays allows to address fundamental physics problems testing for the presence of primordial antimatter and the nature of Dark Matter.
Anti Deuteron Helium Detector (ADHD) project is aiming to study the signature offered by a pressurized Helium calorimeter for the identification of anti-deuterons in cosmic rays.
In particular exotic atoms are...
HELIX (High Energy Light Isotope eXperiment) is a balloon-borne experiment designed to measure light cosmic-ray isotopes, including the propagation clock isotope Beryllium-10, in the energy range from 0.2 GeV/n to beyond 3 GeV/n. HELIX consists of a 1 Tesla superconducting magnet, a high-resolution gas drift chamber, a time-of-flight detector (ToF), and a ring imaging Cherenkov counter (RICH)....
The Trans-Iron Galactic Element Recorder (TIGER) family of instruments are optimized to measure the relative abundances of the rare ultra-heavy Galactic cosmic rays (UHGCR) with Z ≥ 30. Observing the UHGCR places a premium on exposure that the balloon-borne SuperTIGER achieved with a large area detector (5.6 m$^{2}$) and two Antarctic flights totaling 83 days, while the smaller (~1 m$^{2}$)...
The existence of a different state of hadronic matter other than the ordinary nuclear matter, called strange quark matter (SQM), was proposed for the first time in the 1980s. This kind of hadronic matter would be composed by a roughly equivalent number of u, d, and s quarks. SQM could be stable and may constitute the true ground state of hadronic matter. Quarks could therefore be lumped...
The High Energy cosmic-Radiation Detection (HERD) facility has been proposed as one of several main space scientific experiments onboard the China Space Station. HERD is expected to be launched around 2027 and to be operating for at least 10 years. HERD is a China-led international space mission in collaboration with several European institutes from Italy, Switzerland and Spain. Its main...
The next generation magnetic spectrometer in space, AMS-100, is designed to have a geometrical acceptance of 100 m^2 sr and to be operated for at least ten years at the Sun–Earth Lagrange Point 2. Compared to existing experiments, it will improve the sensitivity for the observation of new phenomena in cosmic rays, and in particular in cosmic antimatter, by at least a factor of 1000. The magnet...
A new generation magnetic spectrometer in space will open the opportunity to investigate properties of high energy cosmic rays and to precisely measure the amount of the rare antimatter component in cosmic rays beyond the reach of current missions, addressing with unprecedented accuracy open frontiers in multi-messenger and cosmic ray physics such as the matter-antimatter asymmetry, the...
Flying a superconducting magnet has been the dream of many experiments and projects, both for astroparticles detectors and for radiation shielding. The show stoppers have always been, among other difficulties more manageable, the cryogenics and protection. However the recent progress of the HTS (High Temperature Superconductors) have opened a new way. In particular, REBCO (Rear Earth Barium...
The High Energy cosmic-Radiation Detector (HERD) is a proposed space as-
tronomy payload for the China Space Station. Its main goal is to detect charged
cosmic-rays with energies up to a few PeV and gamma-rays with energies above
100 MeV. The Plastic Scintillator Detector (PSD) is a crucial component of
HERD, and it is designed to identify photons and accurately measure the charge
of...
Direct detection of high energy cosmic rays is strongly constrained by the small effective geometric factors of detectors mainly due to costs and technology of bringing big payloads in orbit. The HERD experiment, a future space experiment which will be installed on the Chinese Space Station in 2026, will take advantage of its innovative geometry and readout systems to have an effective...
Recent experiments measuring cosmic rays have shown discrepancies in the spectra among different observations. The electron spectrum in the region of hundreds of GeV and Carbon and Oxygen spectra were found to differ mostly in flux normalizations, and the discrepancies are larger than the reported experimental errors. Understanding the reasons for these differences is crucial for improving our...
Calorimetric experiments in space of the current and of the next generation measure cosmic rays directly above 10 TeV on satellites in Low Earth Orbit. A common issue of these detectors is the determination of the absolute energy scale for hadronic showers at the highest energies since there are no available facilities for detector testing with particles with energies exceeding several...
