Abstract:

Conductors carrying very high currents show losses of an electromagnetic and a shock compression nature. Electromagnetic losses joule heating in the skin layer, magnetic flux diffusion scale as H3 or Ia3 , where H is the self magnetic field of the current and Ia is the currentconductor periphery shock losses scale as H4 or H3 Ia 4 or Ia 3 depending on the magnitude of I. In experiments where electrical energy must be converged from a large pulsed power supply to a small load, these losses can account for half the orignal energy and limit the magnitude of the energy per unit volume in the load. These considerations may be important for the study of material properties at high energy density.
