IBIS [Imager on Board the Integral Satellite] is an instrument for detailed gamma ray imaging on board of the INTEGRAL satellite, the International Gamma-Ray Astrophysics Laboratory. This satellite is dedicated to observe with high spectroscopic and angular resolution celestial gamma ray sources.... Two main instruments(Spectrometer SPI and Imager IBIS) and two monitors([Optical Monitoring Camera(OMC) ] and X-Ray) will observe in parallel celestial objects of all classes. 2, record 1, English, - instrument%20IBIS

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 1, French, - instrument%20IBIS
