FIG. 16

Bubble fields near the focus of the original (a) and upgraded (b) reflectors operating at 20 kV are shown at t=400 µs (counted from the spark) and t=350 µs, respectively. The shock wave comes from the right. Exposure time is ~1 µs. Frame width is 22 mm. The dotted line in (b) is the −6 dB contour.
