We have demonstrated the formation of stable, symmetric, compact-torus (CT) plasma rings and the subsequent stable, twofold radial compression in coaxial conical electrodes with the ring accelerator experiment. The CT is compressed by {bold J}{times}{bold B} forces from a capacitor bank discharging across the conical electrodes. During compression, the force of the {bold B}{sub {theta}} acceleration field balances the force of the CT poloidal field against the cones, in good agreement with a 2D code. Power amplification factors of {similar to}100 may be possible with an opening switch based on this technique.
