The history of the achievements All-Russian Research Institute Experimental Physics (VNIIEF in Russ. abbr. )i n field ultrahigh magnetic (UHMF) generation and applications fundamental physical studies begins 1952, when Andrey D Sakharov put forward idea cumulation as one possible methods for achieving a controlled thermonuclear reaction [1]. He also proposed two types magnetocumulative generators UHMFs (MC-1) energy (MC-2) [1, 2]. In first them, special device produces initial axial flux cavity cylindrical metal shell (liner). A converging detonation wave is initiated circular explosive charge surrounding liner so that it arrives at external boundary instant time achieves maximum. Under action pressure products, collapses to center, compressing flux. If compression rapid enough,the inthe preserved, themagnetic fieldstrengthonthelineraxisincreasesinversely proportionally squared radius liner, few megagausses. chemical transformed into through kinetic liner. Extensive attempts made many countries reproduce by revealed unexplainable difficulties obtaining fields exceeding 3 MG, which resulted termination work this field. 2. MC-1 cascade generator group researchers VNIIEF headed I Pavlovskii realized number concepts supplementing developing solved problem reproducible UHMFs. First, was make shells from material with controllable electrical conduction. Such state either completely nonconducting or conducts current only direction. At required instant, shock passed material, making conducting all directions. For example, such can be produced closely packed parallel isolated copper wires glued an epoxy compound. Second, unique solenoids
