Abstract
The aim of the study is to analyze the stability of the Energetic Particle Modes (EPM) and Alfven Eigenmodes (AE) in Heliotron J if the electron cyclotron heating (ECH) is applied. The analysis is performed using the code FAR3d [1]. The simulations indicate that the modes with the largest growth rate in the Heliotron J high bumpiness (HB) and medium bumpiness (MB) magnetic configurations are n/m = 1/2 and 2/4 global AE (GAE). On the other hand, the simulations for the low bumpiness (LB) configurations show the destabilization of 1/2 EPM and 2/4 GAE. The simulations for LB configuration show a dominant stabilizing effect of the continuum damping with respect to the increase of the EP β as Te increases. On the other hand, the simulations for the HB and MB configurations indicate that the further destabilization of the AE/EPM caused by the increase of the EP β with Te is larger with respect to the stabilizing effect of the continuum damping.
