Nested-wire arrays on the 20-MA Z -pinch accelerator have produced x-ray powers up to 280{plus_minus}40 TW (a 40{percent} increase over a single array) and an x-ray pulse width of 4thinspthinspns. The short x-ray pulse widths are associated with the formation of tight (1-mm-diameter), uniform pinches at stagnation. Two-dimensional radiation magnetohydrodynamic calculations suggest that the inner array mitigates the growth of implosion instabilities thereby leading to smaller diameter pinches that radiate at higher power than single-wire arrays. {copyright} {ital 1998} {ital The American Physical Society }
