Abstract :
A numerical model for the calculation of the variable inductance during the current-sheet (CS) evolution in plasma-focus (PF) devices is presented. The model represents the CS by an articulated surface of many coaxial conical elements accelerated by the Lorentz force while collecting the mass swept in their paths. The numerical results are validated against the measurements of the time-varying inductance in a 6-kJ PF device, showing good agreement.
