Title: recent results from CLT-K simulations
Abstract: CLT-K code is developed based on a hybrid kinetic-MHD model. For cases of n=2 modes, mode conversion form a TAE-type EPM(rTAE) to a TAE sharing the same toroidal mode number has been observed during the nonlinear stage associated with its frequency downward chirping. Also, the 3/2 magnetic islands associated with n=2 TAE are overserved due to the finite resistivity

Title: "Fine radial structure zonal flow excitation by Beta-induced Alfven eigenmode".
Abstract:The theory present here, is very similar to Prof. Chen and Fulvio Zonca's PRL2012, however, we show here that, zonal structure excited by AEs have a fine radial structure, in addition to the well-know meso-scale structure.
