Development of Real Time System Imaging Software for the Protection of Plasma Facing Components(PFCs) in Wendelstein 7-X — Adnan Ali1, •Marcin Jakubowski1, Thomas Sunn Pedersen1, Alexander Rodatos1, and Henri Greuner2 — 1Max-Planck-Institute for Plasma Physics, Greifswald,Germany — 2Max-Planck-Institute for Plasma Physics, Garching,Germany
One of the main aims of Wendelstein 7-X, an advanced stellarator in Greifswald, is the investigation of quasi-steady state operation of magnetic fusion devices, for which power exhaust is a very important issue. The predominant fraction of the energy lost from the confined plasma region will be removed by 10 so-called island divertors, which can sustain up to 10 MW/Sq-m. In order to protect the divertor elements from overheating and to monitor power deposition onto the divertor elements, 10 state-of-the-art infrared endoscopes will be installed at W7-X and software is under development for real-time analysis of automatic detection of the hot spots and other abnormal events. The pre-defined algorithms[2] designed for early detection of defects e.g. hotspots, surface layers and delaminations during the discharge are being implemented into the software acquiring the images from the infrared cameras and broadcast them to the main Discharge Control System(DCS). This allows for automatic control of the scenario of the discharge in order to assure safe operation of W7-X. The first online tests of the software will soon be performed at GLADIS in Garching.
