Semiconductor high-energy radiation scintillation detector
We propose a new scintillation-type detector in which high-energy radiation generates electron–hole pairs in a direct-gap semiconductor material that subsequently recombine producing infrared light to be registered by a photo-detector. The key issue is how to make the semiconductor essentially transparent to its own infrared light, so that photons generated deep inside the semiconductor could r...
متن کاملHigh - Energy Neutrino Astronomy with the Super - Kamiokande Detector
Presenter: A. Habig ([email protected]), usa-habig-A-abs3-he23-poster The Super-Kamiokande experiment has collected a large sample of high-energy neutrino events. These are primarily atmospheric neutrinos, but a bright enough astrophysical source could also be visible. The data have been examined for possible point and bursting neutrino sources, as well as possible WIMP annihilation signatures. No...
متن کاملHigh-Energy Neutrino Astronomy
Kilometer-scale neutrino detectors such as IceCube are discovery instruments covering nuclear and particle physics, cosmology and astronomy. Examples of their multidisciplinary missions include the search for the particle nature of dark matter and for additional small dimensions of space. In the end, their conceptual design is very much anchored to the observational fact that Nature accelerates...
متن کاملHigh energy neutrino astronomy
Neutrinos are very promising probes for high energy astrophysics. Indeed, many indications suggest that cosmic objects where acceleration of charged particles takes place, e.g. GRBs and AGNs, are the sources of the detected UHECRs. Accelerated hadrons, interacting with ambient gas or radiation, can produce HE neutrinos. Contrarywise to charged particles and TeV gamma rays, neutrinos can reach t...
متن کاملAtmospheric Čerenkov Telescopes: A Next-Generation Detector for Ground-Based High Energy Gamma-ray Astronomy
The construction of the H.E.S.S. (High Energy Stereoscopic System), a superior system of four 12 m imaging atmospheric Čerenkov telescopes, has been completed recently in the Namib desert close to Windhoek, at 1800 m above sea level. This new generation of ground-based gamma-ray detectors has an energy threshold of about 100 GeV in observations at zenith and a sensitivity of about 1% Crab flux ...
