A reflection grating spectrometer works in a very similar way an optical prism does by spreading the incoming light as a function of its different wavelength components. In fact, in the case of XMM, the reflection gratings are nothing more than mirrors with tiny grooves on them.... XMM is the first X-ray mission to fly a reflection grating and will identify lines of elements(like iron, oxygen, silicon, magnesium) common in astrophysical plasmas.  3, record 1, English, - reflection%20grating%20spectrometer

Les données transmises par le spectromètre à grille de réflexion (RGS) permettront de mesurer les caractéristiques des gaz émettant des rayons X mous dans les étoiles chaudes ou provenant des mini-quasars. Ces résultats sont essentiels pour déterminer la relation entre flambées d'étoiles et mini-quasars.  2, record 1, French, - spectrom%C3%A8tre%20%C3%A0%20grille%20de%20r%C3%A9flexion
