“…Les détecteurs gazeux qui lui ont valu le prix Nobel de physique (1992) permettent en effet la conversion, dans un gaz sous pression tel que le xénon, de photons X en électrons. Ces électrons sont amplifiés par effet d'avalanche, c'est-à-dire une multiplication du nombre des électrons dans le champ électrique et détectés par une chaîne électronique adaptée (Babichev et al, 2003).…”

“…First, these sensors occupy very little space and allow for the imaging of large fields in the scanning mode. Secondly, the use of linear scanning sensors helps reduce the amount of scattered radiation reaching the detector; since scattered radiation appears as additional noise in the sensor, a reduction in the amount of scattered radiation would lead to improvement of the contrast and signal-to-noise ratio [4]. Other research groups have developed 1D X-ray sensors by using semiconductors, scintillation materials, and high-pressure gases [5][6][7].…”
