Tore Supra is being strongly modified for the WEST project and the tomographic system will need to be also adapted. The WEST Project aims at implementing an actively cooled tungsten divertor, similar to ITER divertor technology, into the long pulse tokamak Tore Supra (TS). SXR radiation depends mainly on electron and impurity densities and on electron temperature, making it information-rich but difficult to analyze. Generally, the analysis is performed with a 2D tomographic system composed of several cameras equipped with Silicon Barrier Diodes (SBD). The GEM detector is proposed as a novel, reactor-relevant method of SXR detection.
