Destruction of single-tupn solenoids by a strong pulsed magnetic field

Conditions of typical destruction of single-turn solenoids following generation of strong- and superstrong pulsed magnetic fields - the so-called ''slow skin-layer explosion'' are analyzed. Destruction is a metal outburst along the solenoid axis and depends on the ultimate mechanical stress of a solenoid metal cut. To define criteria characterizing appearance of the ''slow-skin-layer explosion'', the equilibrium conditions of a surface layer partion of unit width having thickness equal to the depth of magnetic field penetration into metal are considered. Comparative evaluations of stability of different metals against destructions of such type are carried out. The maximum lengths are presented of the internal surfaces of solenoids without destructions for the following materials: VR-27VP alloy, Ta+3.6%Re alloy, VM-1 alloy, MR-47VP alloy, W, Mo, Zr, Cr, Ta, Nb
