A 24 g aluminum sphere was shot at a sparse array of cylinders with nominal initial projectile velocity of 4 and 5 km/s. Pressure profiles were measured with cased carbon resistor gages at two locations in a projectile impacted water filled cylinder

Several low-Z refractory materials are evaluated for use as the NIF first wall in terms of their cost and ability to survive laser light, target emissions and debris, as well as be cleanable and not outgas excessively. Best performers contain B, C, o

The purpose of the study was to investigate the effect of the impact of a thin membrane on aluminum in the velocity range 6–10 km/s. The impulsive load delivered by a membrane impact will exceed the momentum/area of the membrane because of rebound,

The NIF target chamber interior materials and target designs themselves have to be compatible with survival of the final- optics debris shields. To meet the planned maintenance and refinishing rate, the contamination of the debris shields cannot exce

We have compared sudden shifts in coronal hole boundaries observed by the S-054 X-ray telescope on Skylab between May and November, 1973, within 1 day of CMP of the holes, at latitudes ≤ 40 °, with the long-term evolution of coronal hole area. We

A spectrometer has been developed to meet the requirements of the x‐ray laser effort at Lawrence Livermore National Laboratory (LLNL). The instrument takes advantage of the intrinsically small divergence and size of the lasing source by putting it,

A 22 x Wolter microscope was calibrated after several months of operation in the Lawrence Livermore National Laboratory (LLNL) Inertial Confinement Fusion program. Placing a point x-ray source at the microscope focus, I recorded the image plane spect
