on the International Space Station since May 2011, and operating continuously
since then. By means of the simultaneous use of the Silicon Tracker,
the AMS-02 RICH is able to investigate the isotopic composition of cosmic
rays (CRs) in the kinetic energy range from few GeV/n to ~10 GeV/n
for elements with charge |Z| up... -

The nature and the sources of the cosmic rays of ultra-high energy are not yet elucidated. The cutoff of the spectrum around 50 EeV is now clearly established, but its interpretation is still ambiguous: it can be interpreted as the so-called GZK effect on a flux dominated by protons, or by an upper bound on the acceleration in the sources, or through a complex scenario implying a mixture of...

We review Cherenkov experiments in the Tunka Valley. The experiments span nearly a quarter of a century. They started with a small โtoyโ array and are being presently evolved into a large scale experiment with a wide range of physics goals covering primary cosmic ray studies in the energy range of 1014-1018 eV and very high energy gamma-ray astronomy. We discuss future perspectives of the...

Experimental results obtained with a prototype of a Focused Internal Reflection Cherenkov, equipped with 16 high-granularity arrays of NUV-SiPM and tested at CERN SPS in March 2015, are discussed. The detector was exposed to relativistic ions of 13 and 30 GeV/n obtained from fragmentation of a primary Ar beam. The FDIRC included a single Fused Silica radiator bar optically connected to a...

The High-Altitude Water Cherenkov (HAWC) observatory was completed and began full operation on March 2015, collecting more than one year of data in its full configuration. The detector consists of an array of 300 water tanks, each containing 200 tons of purified water and instrumented with 4 PMTs. Located at an elevation of 4100 m a.s.l. near the Sierra Negra volcano in central Mexico, HAWC...

The IceCube Neutrino Observatory is a cubic-kilometer neutrino telescope located at the Geographic South Pole. Buried deep under the Antarctic glacial, an array of 5160 Digital Optical Modules (DOMs) is used to capture the Cherenkov light emitted by relativistic particles generated from neutrino interactions. The main goal of IceCube is the detection of astrophysical neutrinos, and the...

The SNO experiment was a highly successful experiment that ran from 1999 until 2006. The use of heavy water as a neutrino detection material allowed for the measurement of solar neutrinos in both a charged current channel and a unique neutral current channel. Simultaneous measurements in both channels allowed SNO to demonstrate neutrino flavour change as the solution to the solar neutrino...

When a high energetic particle or gamma-ray interacts with the atmosphere, it induces an air shower. Secondary particles of such showers emit dim and short duration flashes of Cherenkov light that can be measured with Imaging Atmospheric Cherenkov Telescopes (IACTs). For this task, very fast and sensitive photosensors are necessary. To be able to statistically distinguish between showers...

The Gamma Cherenkov Telescope (GCT) is one of the designs proposed for the Small Sized Telescope (SST) section of the Cherenkov Telescope Array (CTA). The GCT uses dual-mirror optics, resulting in a compact telescope with good image quality and a large field of view with a smaller, more economical, camera than is achievable with conventional single mirror...

Neutrino astronomy plays a key role in the exploration of the high-energy sky, due to excellent source pointing capabilities and an unrivaled field of view. Indeed, neutrinos can escape much denser celestial environments than light, thus behaving as tracers of the innermost processes occurring in astrophysical sources, hidden to traditional astronomy, without being deflected by the presence of...

Hyper-Kamiokande is proposed as a next-generation underground water Cherenkov detector having an enormous potential to discover proton decays and leptonic CP violation in neutrino oscillations. Two cylindrical tanks, each with a height of 60m and a diameter of 74m, will be filled with 520,000 metric tons of ultrapure water, a volume approximately 10 times larger than that of predecessor...

The KM3NeT collaboration is building a km3-scale neutrino telescope in the Mediterranean Sea. The current phase of construction comprises the deep-sea and onshore infrastructures at two installation sites and the installation of the first detection units for the ARCA and ORCA detector. At the KM3NeT-It site, 100 km offshore Capo Passero, Italy, the first 32 detection units for the ARCA...

The gamma ray observatory Cherenkov Telescope Array (CTA) is planned to significantly improve upon the sensitivity and precision of the current generation of Cherenkov telescopes. The observatory will consist of several dozens of telescopes with varying sizes and different types of cameras. Of these, the FlashCam camera system is the first to implement a fully digital signal processing chain...

The observation and study of faint signals at very high energy (E > 100 GeV) associated with cosmic phenomena constantly requires the development of advanced technologies and instruments to improve the sensitivity. Imaging Atmospheric Cherenkov Telescopes (IACTs) represent a class of instruments dedicated to the ground-based detection of cosmic VHE gamma ray emission based on the detection of...
