RFX field system design

Theoretical and experimental results show that a stabilized pinch in a flux conserving shell tends to generate a reverse field configuration in the outer regions of the plasma when the pinch ratio theta = B/sub theta wall//B/sub phi average/ is large enough. In RFX it is intended to study this field self reversal and to drive it by supplying the additional energy from a capacitor bank. It is also intended to investigate whether this stable configuration can be set up slowly (approximately 20 ms) and thereby assess the reactor potential
