The laser beam was focused about 1.5 mm downstream from the nozzle.
The inner and outer nozzle pressures were adjusted to achieve various radial distributions over a range of implosion times.
These curves correspond to having the ablation target in the cluster source about 1.5 m from the exit of the supersonic nozzle.
The solid lines in figures 2 and 3 are contours of the satellite volumes obtained at the camera position farthest from the nozzle.
Simple nozzle modifications were suggested that resulted in a substantial calculated yield increase.
These waves are generated near the nozzle lip.
These waves provide the dominant feedback from the wall to the nozzle lip region of the jet.
The reason for this not too infrequent occurrence was traced to leaking nozzle seals or pressure holes or to damage on the flat-plate leading edge.
