Effect of transverse electric fields on a capillary-discharge Z-pinch

Accepted: 14 June 2001
The effect of the transverse-direction electric fields on the stability and dynamics of a capillary-discharge Z-pinch, at conditions for which soft X-ray lasing has been demonstrated, is studied. It is shown that the transverse electric field of the sliding surface discharge provides the instability-free compression and heating of the plasma. Numerical calculations using the MHD model of the discharge yield new predictions for dynamics and stability of the plasma collapse in the presence of the transverse electric fields and explain details of experimental observations without artificial adjustments.
