On the current layer in the run-down phase of the plasma focus discharge

摘要

In the experiments with the 3 kJ plasma focus device in the Sofia University are measured the basic characteristics, namely the discharge current, the current derivative, the soft X-ray and the hard X-ray emission from the plasma. By a set of magnetic probes the velocity of the current sheath during the run-down axial phase is determined. In the last two thirds of the axial phase the current layer velocity is a constant.
