Cherenkov detectors in astroparticle physics

Oral presentation

The High Energy Stereoscopic System (H.E.S.S.) is a system of four Cherenkov telescopes for GeV/TeV gamma-ray astronomy. By observing Cherenkov light emitted by particles in gamma-ray induced air showers the direction and energy of the primary gamma-ray can be reconstructed. A stereoscopic view of the air shower is achieved by combining the information from the four telescopes,...

Cherenkov detectors in astroparticle physics

Oral presentation

The ANTARES detector is the world’s first operating deep-sea neutrino telescope. It is located at a depth of 2475m in the Mediterranean Sea, close to Toulon, France. ANTARES comprises a three dimensional array of 885 photomultipliers, designed to detect the Cherenkov light produced by neutrino-induced muons passing close to the detector. Since June 2008, the construction of the detector is...

Cherenkov detectors in astroparticle physics

Oral presentation

We review the status of the Lake Baikal Neutrino Experiment. Preparation towards a km3-scale Gigaton Volume Detector (GVD) in Lake Baikal is currently a central activity. A prototype string for the future km3-scale Baikal neutrino telescope has been deployed and is fully integrated into the NT200+ telescope. We describe preliminary design and expected sensitivity of the GVD telescope, and...

48. The Major Atmospheric Gamma Ray Imaging Cherenkov Telescope

Cherenkov detectors in astroparticle physics

Oral presentation

MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes (IACTs). During the construction novel technologies have been developed, which nowadays represent the state of the art techniques on the market. The 17m diameter reflector is composed of light weight sandwich structured aluminium and glass mirrors, mounted on a carbon fiber tube dish structure. The overall focusing is kept at...

76. The AMS~02 RICH detector: performance during ground-based data taking at CERN

Cherenkov detectors in astroparticle physics

Oral presentation

The Alpha Magnetic Spectrometer (AMS), whose final version AMS 02 is to be installed on the International Space Station (ISS) later this year, is a detector designed to measure charged cosmic ray spectra with energies up to the TeV region and with high energy photon detection capability up to a few hundred GeV, using state-of-the art particle identification techniques. Among several...

59. A new 1 km**2 EAS Cherenkov Array in the Tunka Valley

Cherenkov detectors in astroparticle physics

Oral presentation

A new EAS Cherenkov array has recently been put into the full operation in the Tunka Valley in Siberia, Russia. The main goal of the new detector is to study primary cosmic rays energy spectrum and mass composition in the energy range of 10**15 eV -10**18 eV. The array consists of 133 optical modules covering 1 km**2 area. The optical modules (OMs) are assembled in 19 clusters with 7 OMs in...

Cherenkov detectors in astroparticle physics

Oral presentation

The Cerenkov Telescope Array (CTA) is a project of building a High Energy (10 GeV to 100 TeV) gamma ray observatory. The CTA consortium is organized in workpackages dedicated to the electronics, the telescope structure, the focal plane instruments and other topics. In this talk, I will first give a brief overview of High Energy gamma ray astronomy. Next, I will describe the status of the work...

Cherenkov detectors in astroparticle physics

Oral presentation

KM3NeT denotes a research infrastructure in the Mediterranean deep sea, hosting a neutrino telescope with an instrumented volume of several cubic kilometres and interfaces for devices serving earth and sea science research. The technical design of the neutrino telescope will be presented, with particular focus on light detection and data acquisition. Its major physics objectives will be...

Cherenkov detectors in astroparticle physics

Oral presentation

The maximization of the photon detection efficiency (PDE) is a key issue in the development of cameras for Imaging Air Cherenkov Telescopes (IACT). Geiger-mode Avalanche Photodiodes (G-APD) are a promising candidate to replace the commonly used photomultiplier tubes by offering a larger PDE and a facilitated handling. The FACT project (First G-APD Cherenkov Telescope) evaluates the feasibility...
