by creating a self-generated toroidal field. The tilt mode has also been stabilized in FRC experiments by increasing the ion gyroradii. The magnetorotational instability. This mode causes a rotating elliptical distortion of the plasma boundary, and can destroy the FRC when the distorted plasma comes in contact with the confinement chamber. Successful stabilization methods include the use of a quadrupole stabilizing field, and the effects of a rotating magnetic field (RMF). Experiments Spacecraft propulsion Field-reversed configuration devices have been considered for spacecraft propulsion. By angling the walls of the device outward, the plasmoid can be accelerated in the axial direction and out of the device, generating thrust.
