Sample interview questions: How would you approach the problem of plasma flow control in a non-axisymmetric experimental setup?

Sample answer:

  1. Understand the Plasma Flow Dynamics:
  2. Begin by characterizing the plasma flow in the non-axisymmetric setup using diagnostic techniques such as Langmuir probes, spectroscopy, and imaging.
  3. Identify key parameters like density, temperature, and velocity profiles to establish a baseline understanding of the plasma behavior.

  4. Analyze Magnetic Field Topology:

  5. Investigate the magnetic field configuration using magnetic field sensors or modeling tools.
  6. Determine the locations and strengths of field lines, null points, and separatrix surfaces to understand how they influence plasma flow

  7. Develop a Theoretical Model:

  8. Construct a theoretical model based on magnetohydrodynamics (MHD) equations or kinetic theory to describe the plasma flow in the non-axisymmetric geometry.
  9. Use numerical simulations to solve the model and predict the plasma behavior under various conditions

  10. Control Techniques:

  11. Explore different plasma control techniques, such as:
