Very High Energy Gamma Ray Astronomy and Cosmic Ray Physics with the ARGO-YBJ experiment
Gamma ray astronomy at energies 1011 1013 eV, which are strictly related to the identification and study of the cosmic ray acceleration sites, is the main scientific goal of the ARGO-YBJ experiment. The detector, which is now being assembled in Tibet (China) at 4300 m a.s.l., is a full coverage Extensive Air Shower array consisting of a carpet of Resistive Plate Chambers covering a surface of a...
متن کاملFuture science issues for Galactic very-high-energy gamma-ray astronomy
This work intends to provide a brief summary of some of the Galactic science issues for the next generation of very high energy (VHE) instruments. The latter is here generically understood, as an instrument or set of instruments providing about one order of magnitude more sensitivity at its central energy (at about 1 TeV), but extending the observational window to have a real broadband capabili...
متن کاملThe Cat Imaging Telescope for Very-high-energy Gamma-ray Astronomy
The CAT (Cherenkov Array at Th emis) imaging telescope, equipped with a very-high-deenition camera (546 fast phototubes with 0:12 spacing surrounded by 54 larger tubes in two guard rings) started operation in Autumn 1996 on the site of the former solar plant Th emis (France). Using the atmospheric Cherenkov technique, it detects and identiies very high energy-rays in the range 250 GeV to a few ...
متن کاملThe use of silicon photomultipliers for very high energy gamma ray astronomy: the optical issues
Due to its sensitivity and speed, the detector still widely used in Cerenkov astrophysics experiments remains the Photo-Multiplier Tube (PMT). However, there are some disadvantages to the PMT technology: the rather poor quantum efficiency, the use of high voltages, the high cost when used in large number in a matrix arrangement and a subsequent large weight. Hence, we have investigated the poss...
متن کاملThe Atmospheric Cherenkov Imaging Technique for Very High Energy Gamma-ray Astronomy
One of the last frontiers of the gamma-ray sky is that characterized by the distribution of TeV photons. These photons can be detected relatively easily with ground-based detectors (constituting a TeV ”window” in the atmosphere) and thus the detection of sources did not have to await the availability of space platforms. In practice although the technology was available at an early date, it requ...
