Gamma Ray Detection

The Universe in Gamma-Rays by Volker Schonfelder,

Gamma-ray astronomy began in the mid-1960s with balloon satellite, and, at very high photon energies, also with ground-based instruments. However, the most significant progress was made in the last decade of the 20th century, when the tree satellite missions SIGMA, Compton, gamma ray detection and Beppo-Sax gave a completely new picture of our Universe gamma ray detection and made gamma-ray astronomy an integral part of astronomical research. This book, written by well-known experts, gives the first comprehensive presentation of this field of research, addressing both graduate students gamma ray detection and researchers. Gamma-ray astronomy helps us to understand the most energetic processes gamma ray detection and the most violent events in the Universe. After describing cosmic gamma-ray production gamma ray detection and absorption, the instrumentation used in gamma-ray astronomy is explained. The main part of the book deals with astronomical results, including the somewhat surprising result that the gamma-ray sky is continuously changing.

Gamma ray burst - Gamma-ray bursts (GRBs) are the most luminous physical phenomena in the universe known to the field of astronomy. They consist of flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow.

Gamma-Ray Amplification by Stimulated Emission of Radiation - Gamma-Ray Amplification by Stimulated Emission of Radiation (GRASER) describes a gamma-ray laser that operates between energy levels established by metastable isomeric transitions in the nucleus. Edward Teller established a now-defunct project to develop GRASER weaponry.

Gamma-ray Large Area Space Telescope - The Gamma-ray Large Area Space Telescope, or GLAST, is a future space-based gamma-ray telescope, designed to explore the high-energy Universe. It will study astrophysical and cosmological phenomena such as active galactic nuclei, pulsars, other high-energy sources, and dark matter.

Gamma ray spectrometer - Gamma Ray Spectrometers (GRS) are instruments that use the gamma-ray part of the spectrum to look for the presence of 20 elements from the periodic table, and have been used in the exploration of Mars, the Eros asteroid and the Moon. Their neutron detectors can look for water and ice in the soil by measuring neutrons.

Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe would result in gamma-ray emission. Gamma-rays coming from space are mostly absorbed by the Earth's atmosphere. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. The first gamma-ray telescope carried into orbit, on the Explorer-XI satellite in 1961, picked up fewer than 100 cosmic gamma-ray photons. Such a background would be expected from the interaction of cosmic rays (very energetic charged particles in space) with gas found between t... These appeared to come from
