Gamma-ray Detectors Introduction - Imagine the Universe!
2018年12月11日 · Gamma rays are detected by observing the effects they have on matter. A gamma ray can collide with an electron and bounce off it like a billiard ball (Compton scatter) or it can push an electron to a higher energy level (photoelectric ionization).
Gamma-Ray Detectors - an overview | ScienceDirect Topics
2020年2月25日 · Gamma-ray detectors are devices that can achieve high spatial resolution for imaging gamma rays, improving the performance of gamma cameras by being compact and lightweight. They typically consist of pixelated arrays and photomultiplier modules, along with miniature electronics for data acquisition and processing.
GeGI | The World’s Most Advanced HPGe Gamma Ray Imager
Quickly explore this brief pinhole-imaging demonstration of the most sophisticated gamma-ray detector in the world, the GeGI®. Harness the power to detect, locate, and quantify even small amounts of radioactivity.
Gamma spectroscopy - Wikipedia
Gamma spectroscopy detectors are passive materials that are able to interact with incoming gamma rays. The most important interaction mechanisms are the photoelectric effect, the Compton effect, and pair production.
Gamma and X-Ray Detection - Mirion
NaI is still the dominant material for gamma detection because it provides good gamma ray resolution and is economical. However, plastics have much faster pulse light decay and find use in timing applications, even though they often offer little or no energy resolution.

NASA’s New Detectors Could Improve Views of Gamma-Ray Events
2023年6月6日 · NASA scientists are developing upgraded gamma-ray sensors to reveal more details about black hole outbursts and exploding stars. All three versions of AstroPix sensor chips are on display from the oldest on the left to version 3 on the right. Version three, which began testing in April 2023 has bigger pixels and improved functionality.
Gamma-ray spectrometer - Wikipedia
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.
