Abstract

The physics process in a new kind of plasma magnetic field compression generator (MFCG) without the preliminary magnetic field is studied with a zero-dimensional theoretical model. It is found that the plasma liner is accelerated in the conduction stage and is decelerated in the compression stage. The geometry parameters of MFCG effect the load current amplification significantly. The geometry parameters need to be chosen carefully to make the acceleration space and the deceleration space being suitable for the generator circuit and the injected plasma liner to obtain the optimal amplification factor. For the given driven circuit, the typical amplification factor of load current is greater than 2.
