Název v původním jazyce

Comparative analysis and new post-processing methods for plasma tomography at tokamaks

Popis výsledku v původním jazyce

The JET tokamak is equipped with extensive diagnostic systems for tomography, including bolometers and soft X-ray (SXR) detectors. The tomographic reconstructions presented in this contribution were obtained using an algorithm based on Tikhonov regularisation and Minimum Fisher information. A new method for subsequent interpretative analysis of the tomographic reconstructions will be introduced. It is based on a comparison of radiated power from different regions of reconstruction, that can be defined by a rectangle or by a flux surface. The method was also used for comparative analysis of data obtained by reconstructing signals from different detectors. Both combined and separate reconstructions will be analysed. Example applications are presented, showing electron temperature drop, sawteeth instability and transport after laser blow-off.
