HAWC August 14, 2014 HAWC with the Pico de Orizaba in the background, August 2014. The High Altitude Water Cherenkov Experiment or High Altitude Water Cherenkov Observatory (also known as HAWC) is a gamma-ray and cosmic ray observatory located on the flanks of the Sierra Negra volcano in the Mexican state of Puebla at an altitude of 4100 meters, at
A gamma-ray spectrometer (GRS) is an instrument for measuring the distribution (or spectrum—see figure) of the intensity of gamma radiation versus the energy of each photon. The study and analysis of gamma-ray spectra for scientific and technical use is called gamma spectroscopy , and gamma-ray spectrometers are the instruments which observe ...
It detects ionizing radiation such as alpha particles, beta particles, and gamma rays using the ionization effect produced in a Geiger–Müller tube, which gives its name to the instrument. [2] In wide and prominent use as a hand-held radiation survey instrument, it is perhaps one of the world's best-known radiation detection instruments.
Gamma-ray spectrometry, on the other hand, is the method used to acquire a quantitative spectrum measurement. [1] Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced.
In general, indirect detection searches focus on either gamma-rays, cosmic-rays, or neutrinos. [2] There are many instruments that have been used in efforts to detect dark matter annihilation products, including H.E.S.S. , VERITAS , and MAGIC ( Cherenkov telescopes ), Fermi Large Area Telescope (LAT), High Altitude Water Cherenkov Experiment ...
High energy beta detection, where the beta enters via the side of the tube and interacts directly with the gas, but the radiation has to be energetic enough to penetrate the tube wall. Low energy beta, which would penetrate an end window, would be stopped by the tube wall. Low energy gamma and X-ray detection.
Alpha scintillation probe under calibration. The most commonly used hand-held survey meters are the scintillation counter, which is used in the measurement of alpha, beta and neutron particles; the Geiger counter, widely used for the measurement of alpha, beta and gamma levels; and the ion chamber, which is used for beta, gamma and X-ray measurements.
Gamma rays were first discovered and studied in 1900 by a French chemist, Paul Villard while observing radiation from radium. [6] However, the first quantitative analysis of gamma radiation is credited to Rutherford and Andrade in 1914. This earliest technique was accomplished by diffraction spectroscopy using a rock-salt crystal. [16]
