Paper Abstract

The Schlumberger SYCOSCAN is a radioscopic control system designed to inspect freight containers and vehicles by X-rays. The X-ray detection is based on a modified version of a multiwire proportional chamber (MWPC) patented by Schlumberger. The MWPC principle was discovered by 1992 Physics Nobel Prize Winner G. Charpak. We present the detector's working principle. It presents simultaneously a high spatial resolution, a good detection efficiency, a high intrinsic gain and high dynamics. We will compare the SYCOSCAN detector to conventional scintillator/photodiode combinations.
