The dynamics of plasma cylinder compression by current 
pulses with a rise time of 100 nsec in the Z-pinch 
geometry has been considered. The numerical simulation has been performed 
in the approximation of one-dimensional magnetic radiation gas dynamics. 
In the calculations, real thermodynamic, transport, and optical properties 
of the plasma have been used. The radiation transfer is described 
in the multigroup approximation by the photon energy. The calculations 
have been performed for a pinch in xenon (radius 0.5 cm, energy E0 = 10-30 J, 
maximum current 30 kA). A detailed pattern of the dynamics of pinches 
has been investigated and the energy-to-radiation conversion efficiency 
has been determined.
