Abstract:

The hydromagnetic model of the evolution of a plasma puff in a B sub z field described by Waelbroeck has been used to analyze the characteristics of the plasma produced by the APL conical pinch gun. The analysis is based on fitting the signals induced in single turn magnetic pickup loops by the passing plasma. In the cases studied good fits to the signals have been achieved and the characteristic parameters of the plasma found. This analysis applied to plasma generated by the APL theta-pinch gun has not been successful. In the two cases studied, the lack of good fits is attributed to the presence of a sizeable amount of trapped field in the puff which is present along the entire flight path through the B sub z field.
