In this paper we report the results of experiments that compare the x-ray emission from a laser spot in a radiation-filled hohlraum to that from a similar laser spot on a simple disk target. The studies were done using the Nova laser facility [J. D.

A number of optical streak cameras are routinely operated for experiments at the Lawrence Livermore National Laboratory Nova laser facility. We report results from a study of the accuracy and reproducibility of the sweep rate. The sweep rates, measur

A four‐frame gated x‐ray microscope has been developed for the study of inertial confinement fusion. Four x‐ray images were obtained by introducing flat, grazing incidence mirrors into the converging annular ray bundle of a previously developed

We have developed a large area short pulse framing camera that is capable of sixteen frames and shutter times of 40 ps per frame. This is accomplished with a high fidelity electrical circuit and a L/D equals 20 microchannel plate, driven by a short p

Two decades of development driven largely by military night vision applications has led to the availability of a wide selection of microchannel plates for use by the scientific community. Microchannel plates (MCPs) are electron multipliers which reta

High-speed, high x-ray energy imaging of implosions is a key diagnostic technique in the glass laser implosion program in the USA. With the correct x-ray energy, time-gated images can measure the symmetry and mix of the imploding shell into the stagn

High-gain laser-driven intertial confinement fusion requires that the target be driven to high densities while maintaining a high degree of symmetry. The need to measure, with minimal velocity blurring, both the symmetry of the imploding shell and th

Future multibeam laser-fusion experiments will require that beam powers be determined with better than 5% precision over a range approaching 40 to 1. In this paper, statistical, dispersive, and nonlinear factors which most influence such measurements
