[Une nouvelle source de rayons X de haute qualité]
Les sources de photons par effet Compton inverse apparaissent aujourd'hui particulièrement prometteuse étant données les avancées technologiques dans le domaine des lasers et des accélérateurs. Il est désormais possible d'envisager leur utilisation en tant que source ultra-compacte de radiations. Elles peuvent fournir des pulses de rayons X très courts avec un flux moyen important. De plus, la relation directe entre l'énergie des rayons X produits dans l'axe de la collision photon–électron permet d'obtenir des faisceaux quasi-monochromatiques avec un simple collimateur. Les projets de telles sources permettent d'envisager des flux de
Compton based photon sources have generated much interest since the rapid advance in laser and accelerator technologies has allowed envisaging their utilisation for ultra-compact radiation sources. These should provide X-ray short pulses with a relatively high average flux. Moreover, the univocal dependence between the scattered photon energy and its angle gives the possibility of obtaining a quasi-monochromatic beam with a simple diaphragm system. For the most ambitious projects the expected performance takes into account a rate of
