Very large magnetic fields were first produced using electrical discharges through coils. More recently, many researchers have used the method of explosively-driven flux compression to generate megagauss magnetic fields. We reported using Proto-II, a 10 TW electrical accelerator, to directly generate fields up to 1.5 kT (15 MG) in a coaxial geometry. The development of even larger electrical accelerators has now allowed us to directly generate magnetic fields of magnitudes equivalent to the largest values attained with explosively-driven flux compression generators. In this paper we report experimental results in which the Saturn accelerator delivered a peak current of 10.5 MA to a 2-mm diameter tungsten rod, thereby generating a peak magnetic field of {approximately}2.1 kT (21 MG). We also show the results of one-dimensional (1-D) calculations which show that peak fields of 2.1 kT were achieved at the surface of the tungsten rod. We will discuss possible constraints on the production of megagauss magnetic fields by either direct current generation or by explosively-driven flux compression using metallic liners. 16 refs., 11 figs.
