End loss reduction in linear devices by means of oscillating multiple mirrors

We consider briefly the effects of adding oscillating multiple mirrors to a linear theta-pinch like plasma column. The plasma parameters chosen for the example shown correspond to those of a previously proposed linear reactor configuration. We show that it should be easy to dynamically stabilize the inherently unstable bumpy theta-pinch which results from adding static mirrors to a linear theta-pinch. We show further that the energy in the dynamic stabilization circuit can be used for plasma heating since the oscillating field components give rise to strongly Landau damped ion-acoustic waves.
