We have magnetically driven a tapered-thickness spherical aluminum shell implosion with a 12.5 MA axial discharge. The initially 4 cm radius, 0.1 to 0.2 cm thick, [plus minus]45[sup [degree]] latitude shell was imploded along conical electrodes. The implosion time was approximately 15 [mu]sec. Radiography indicated substantial agreement with 2D-MHD calculations. Such [ital calculations] for this experiment [ital predict] final inner-surface implosion velocity of 2.5 to 3 cm/[mu]sec, peak pressure of 56 Mbar, and peak density of 16.8 g/cm[sup 3] ([gt]6 times solid density). The principal experimental result is a demonstration of the feasibility of electromagnetic-driven spherical liner implosions in the cm/[mu]sec regime.
