    Abstract
  • A kind of rectangular cross-section, ferromagnetics magnetic core is selected to fabricate a magnetic switch used as the discharge switch of the solid-state accelerator. B-H curves at different locations on the magnetic core are measured with the pulsed capacitor method. Results illustrate that the properties of these cores are good enough for the utilization of the magnetic pulse compression and the shapes of the B-H curves on different sides of cores are similar. PSpice is employed to analyze the circuit of the system including the magnetic switch used as the discharge switch. Results show reasonable agreement with the theoretical prediction. Experimental research was carried out on the discharge switch driven by a rolled strip pulse forming line. A quasi-square pulse with the peak voltage of 9 kV, and pulse duration (FWHM) of 230 ns was obtained on low resistance load. The rise-time of the pulse was less than 80 ns.
