Description
It has been previously shown in mirror experiments that the use of multiple-frequency ECRH increased the pressure of trapped, high-energy electrons. In the initial phases of the Levitated Dipole Experiment (LDX), ECRH will be applied with multiple frequencies between 2.45 and 28 GHz in order to produce a population of energetic electrons at high β. The pressure profile will be controlled by adjusting the relative power of the ECRH sources. The effect of the pressure profile on plasma stability and confinement is a principal area of study for the LDX experiment. Ray tracing in the LDX geometry using a finite temperature code indicates that single-pass absorption can be obtained. ECRH has several other uses within LDX, such as formation and control of convective cells and the study of heating of over-dense thermal plasmas
