Examination of High-Density Plasma Heating on the GAMMA 10/PDX Central Cell with 3D Wave Analysis Code

In GAMMA 10/PDX, ion heating is achieved using slow wave in the cyclotron frequency absorbed near resonance layer. However, high-density plasma, less likely to be excited due shielding effect. To overcome this challenge, researchers have investigated difference (DF) waves by nonlinear interaction of fast been investigated. The can propagate core plasma even making DF-waves an efficient option for heating. This study has suggested that a DF-wave with left-handed polarization, which as wave, effective plasma. characteristics were analyzed three-dimensional (3D) analysis code, TASK/WF3D, investigate absorption results showed when antenna positioned inside simulate heating, higher than low-density These indicate plasmas.
