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

L'instrument IBIS à bord d'INTEGRAL [est] chargé de fournir des images précises du ciel dans un domaine d'énergie allant de 20 keV à 10 MeV. [Cet instrument] est l'héritier direct du télescope SIGMA. Sa conception est en effet très semblable, alliant un masque codé à un ensemble détecteur à base de caméras gamma, le tout étant protégé des rayonnements parasites par des blindages actifs et passifs. L'originalité d'IBIS (Imager on Board the Integral Satellite) réside surtout dans les performances de l'ensemble détecteur qui devrait permettre d'atteindre une sensibilité dix fois meilleure que celle de SIGMA. Pour couvrir un domaine d'énergie de près de 3 ordres de grandeur, il a fallu recourir à l'utilisation de deux caméras. La première, ISGRI (Integral Soft Gamma-Ray Imager), fonctionne à basse énergie (20 keV - 1 MeV). La seconde, PICsIT (PIxellated CsI Telescope), mesure les photons de plus haute énergie (150 keV - 10 MeV).  2, record 4, French, - instrument%20IBIS
