The time to the flrst bounce of the dynamic pinch has been measured and compared with the formula derived by Rosenbluth. The theoretical dependence on gas pressure and electric field strength is verified. A coil system is described which has been used to detect kink instabilities. When an axial magnetic field of sufficient strength has been applied, it has become impossible to detect the kink instabilities which are shown to destroy the pinch in zero and moderate magnetic fields. Stability observations have been carried over several periods of the discharge. This revealed that the plasma performs a contraction and seems to be stable in the subsequent periods also. Finally, an investigation has been made of the pressure dependence of the electro-mechanical oscillation which is performed by the plasma sheath before reaching equilibriuma where the axial and azimuthal magnetic fields balance.
