Transition Processes during Compression of Cylindrical Shells in a Strong Magnetic Field,
Abstract
A calculated arrangement has been worked out for compression of thin-walled metallic shells in the field of a single-turn solenoid, taking into account penetration of the field into the shell, its heating up by vortex currents, redistribution of current over the surface of the solenoid, and the presence of a matching transformer in the discharge loop. The accepted inertial model of deformation is applicable with beta > 0.2. At smaller values the influence of the forces of resistance to deformation are significant. The most important factors which determine the efficiency of acceleration in the arrangement which is considered are the active resistance and inductance of the primary circuit, and also the fact that part of the current of the solenoid flows on the ends of the solenoid and do not participate in the creation of the working field.
