Deconvolution of JET Core LIDAR Data and Pedestal Detection in Retrieved Electron Temperature and Density Profiles

The high-confinement mode (H-mode) is considered as one of the most promising regimes of operation of the thermonuclear reactors. The H-mode is characterized by the formation of an edge pedestal region in which steep gradients in the density and temperature are observed as a result of formation of a particle and energy transport barrier near the plasma edge. The Lidar Thomson scattering diagnostic has been successfully used for reliable and robust measurement of the electron temperature Te and density ne profiles on JET. The resolution of 12-15cm is however practically insufficient for resolving the narrow pedestal area.
