Gamma rays are electromagnetic radiation at the short-wavelength, or high-frequency, end of the electromagnetic (EM) spectrum, which ranges from gamma rays (short) to radio (long). 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 and collect such data. Because the energy of each photon of EM radiation is proportional to its frequency, gamma rays have sufficient energy that they are typically observed by counting individual photons. 2, record 1, English, - gamma%2Dray%20spectrometer

Un spectromètre de temps de vie associé à une source22Na(NaCl) permet d’enregistrer le temps qui sépare la détection d’un gamma d’énergie 1, 28 MeV [mégaélectronvolt] de celle d’un des gamma d’annihilation à 511 keV [kiloélectronvolts]. Il enregistre ainsi le temps que «vit» un positon entre sa naissance et sa disparition. Le spectromètre est formé de deux voies de détection de photons gamma qui sont couplées à un système de coïncidence rapide-rapide. L'une des voies détecte le photon gamma à 1, 28 MeV et génère un signal qui date son émission(voie start). La seconde voie détecte l'un des photons gamma d’annihilation à 511 keV et génère un signal qui date son émission et est retardé d’une durée fixe par rapport à la voie à 1, 28 MeV(voie stop). Le module de coïncidence est ouvert par le signal issu de la voie à 1, 28 MeV et fermé par celui de la voie à 511 keV. Il délivre un signal dont l'amplitude est proportionnelle au temps qui sépare la détection de ces deux signaux. 1, record 4, French, - spectrom%C3%A8tre%20de%20temps%20de%20vie
