摘要：

Nested-wire arrays on the 20-MA Z-pinch accelerator have produced x-ray powers up to 280 +/- 40 TW (a 40% increase over a single array) and an x-ray pulse width of 4 ns. The short x-ray pulse widths are associated with the formation of tight (l-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.
