Abstract

Abstract

Theoretical analysis and experiments have been done to find out the factors which decide the self-restoration ability of low remanence magnetic cores. The results show that in the right working circuit, the cores with appropriate pulse permeability can self-restore to its remanence within 1 s. Two sample cores have been proved to satisfy all the three demands to be cavity cores of a multi-pulse inductive accelerator, i.e., the cores’ self-restoration time is less than 1 μs, its pulse average permeability is greater than 300 and flux density change area is greater than 0.7 T. The magnetic cores restoration problem in MHz repeat frequency high voltage multi-pulse is likely to be solved by choosing the right material of the cavity cores of the multi-pulse inductive accelerator．
- low remanence magnetic cores,
- self-restoration,
- mhz repeat frequency,
- high voltage multi-pulse
