Experiments with Pulsed Magnetic Cusps

Experiments with a simple pulsed magnetic field in cusped geometry are described. The plasma is generated inside the containment region rather than injected from an external source. It was found that creation of the plasma by a linear pinch discharge is most successful. Only qualitative studies have been carried out so far, using time-resolved visual observation of the plasma. Well-defined plasma bodies located in the central region between the coils were photographed. In order to make them clearly visible, a few percent of argon was added to the hydrogen.
