Approaching Plasma Density Control in Non-Axisymmetric Experimental Setups
-
Model the plasma behavior: Utilize computational models to simulate the plasma dynamics and optimize density control strategies in the non-axisymmetric geometry. This includes considering factors such as magnetic field configuration, wave propagation characteristics, and boundary conditions.
-
Employ advanced diagnostics: Implement diagnostics capable of providing real-time measurements of plasma density, such as interferometry, Thomson scattering, or Langmuir probes. This enables accurate monitoring and feedback control of density.
-
Utilize electromagnetic wave manipulation: Leverage electromagnetic waves, such as microwaves or millimeter waves, to non-invasively heat, excite, or modify the plasma properties. By controlling the amplitude, frequency, and polarization of waves, plasma density can be influenced.
