Computer Analysis of Megagauss Field Generation by Condenser Bank Discharge

This is the authors' abstract. We don't add key points for this paper.

Experiments on the generation of very high magnetic fields in the megagauss range (>100 T) by use of a large current from condenser banks are analysed by a computer simulation. The analysis is performed for the electromagnetic flux compression with both the θ-pinch and z-pinch configuration as well as the single-turn coil technique. The distribution of the current and temperature of the liner or the coil is appropriately treated by a 2-dimensional analysis dividing the cross-section into many mesh sections. The deformation of the liner during the implosion is calculated by a finite-element method. A good agreement between the calculation and recent experiments was obtained.
