First exploitation results of recently developed SXR GEM-based diagnostics at the WEST project

This contribution outlines the first preliminary acquisition data obtained by the GEM diagnostics on WEST. It was designed to monitor the radiation of impurities with a particular focus on the challenges of the elaborated plasma imaging technology in the area of SXR radiation. The details of the developed diagnostics and preliminary results obtained within the commissioning phase of the diagnostics at the WEST Project are provided. It is shown that both spatially and spectrally resolved calibrated data could be collected. A comparison with other WEST diagnostics manifests good qualitative agreement. Currently, the developed system records rather high energy part of the SXR radiation (above 4 keV), that nevertheless still could be useful to assess an intensification of the erosion.
