MHD simulations of plasma dynamics in pinch discharges in capillary plasmas

Magnetohydrodynamic simulation results related to the capillary discharge d ynamics are presented. The main physical process that should be taken into account is the ablation of the capillary wall material evaporated by the he at flux from the capillary plasma. The possible applications of the capilla ry discharges related to the physics of the X-ray lasers and the use of the capillary plasma to provide a guiding for ultrashort high-intensity laser pulses over a distance greater than the defocusing length are discussed.
