                         carried out in a vacuum arc plasma centrifuge to investigate the 
                         influence of residual gases in these parameters. The measurements 
                         were performed in a magnesium plasma utilizing a cylindrical 
                         Langmuir probe. Hidrogen, helium and argon were used a residual 
                         gases with pressure varying in the range of 1x10-4 to 1x10-1 Pa. 
                         With no gas (1x10-4 Pa) the electron temperature and plasma 
                         density are pratically constant over the entire plasma current 
                         pulse. The introduction of a gas change this picture appreciably. 
                         For the range of 10-2 - 10-1 Pa the electron temperature decrease 
                         about 50% while the plasma density increases by the same factor
