Abstract Text:
We use the Q2D code to simulate the formation of a Reversed Field Configuration by injecting neutral beams in a mirror-confined plasma. Q2D is a 2D MHD code with separate ion and electron temperatures, a fluid model for the neutral gas, and is coupled with a 3D Monte Carlo code, which is used to calculate neutral beam injection, fast ion orbits and their interaction with the thermal plasma. We study different beam injection angles, impact parameters, equilibrium magnetic fields and neutral beam current, and analyze the different types of fast ion orbits and their effect on field reversal. The simulations show that the fast ion current can reverse the magnetic field if the current density is sufficiently high. Equilibria with higher magnetic field require higher current density for FRC formation.
