Resumo

The use of Z-pinch facilities makes it possible to carry out well-controlled and diagnosable laboratory experiments to study laboratory jets having scaling parameters close to those of jets of young stars. It was found that a low-concentration region is formed after the first supersonic ejection, allowing subsequent ejections to propagate collimated. An exact solution of the generalized Grad-Shafranov equation for axisymmetric plasma flows was also obtained and the interaction of the plasma ejection with the gas was numerically modelled, which agrees well with the experimental data.
