“…HEMGs with diameters of 160, 200, and 400 mm have been developed, producing the output electromagnetic energy of 0.5-20 MJ. Such HEMGs combined with explosion current switch are used in liner experiments R-DAMAGE [18], [19] and for heating thermonuclear plasmas in experiments with the MAGO/MTF chamber [20]- [25] Here MAGO/MTF is for the MAGnitnoe Obzhatie (Russian for "MAGnetic Compression")/Magnetized Target Fusion. Such HEMGs are used for the initial feeding of the disc EMGs, which are the highest power EMGs among the EMGs.…”

Presented are the fundamentals of a consistently electrodynamic 2-D technique of designing helical explosive magnetic generators by numerical simulation on the basis of nonuniform equation for the vector potential with a priori set right-side term. The technique is demonstrated by solving a 1-D problem. A model 2-D problem a closed coil over a tube is analyzed. A coil current rupture is simulated. Concepts of vacuum inductance and free magnetic flux are discussed. Magnetic flux losses in the skin layer and free magnetic flux variation are calculated for an instant compression of an electric contour. A 2-D nonstationary problem a closed coil over a tube is solved. A critical mode of the generator operation is analyzed. A technique is described for solving a problem multiturn helix over a tube.Index Terms-Fully electrodynamic method, helical high-explosive magnetic generator (EMG), numerical simulation, vector potential.
