Abstract
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.
