Image of FIG. 1.
FIG. 1.

Wire locations and point-projection lines-of-sight for the closely spaced wire configuration (not to scale). The south -pinch was timed to image the wire pairs earlier, while the north -pinch was timed to image the pairs later in time. The laser backlighter beams (not shown) passed through the array from left to right.

FIG. 2.

An enhanced contrast, false color radiograph from shot 762 showing 1.9 mm of two -diameter tungsten wires spaced apart at 93 ns and 1.13 MA on the cathode side of the fiducial region (light rectangle). The corresponding correlated lineouts are shown below.

FIG. 3.

(a) An enhanced contrast radiograph from shot 800, taken using the COBRA-STAR imaging system of ten tungsten wires with diameters at 100 ns and 1.0 MA. The monofilament obscured one of the wires. Lineouts were extracted from the dotted regions within the false color portion of the image. (b) The corresponding lineouts from wires in the radiograph at local magnification.

FIG. 4.

Correlation coefficient vs wire separation with 95% confidence intervals for various wire diameters and array diameters in the spatial domain (left) and in the spatial-frequency domain (right) with the Dc component excluded.

Image of FIG. 5.
FIG. 5.

(a) Current shunting mechanism for correlated ablation of two neighboring wires prior to gap formation (b) and after a break has formed in left wire.

Image of FIG. 6.
FIG. 6.

(a) Magnetic compression mechanism for correlated ablation of two neighboring wires in the initial stage (b) and after break has formed in left wire. For clarity, only the plasma streamers from the lowest pair of wires are shown.
