We report experimental determinations of the elastic component of the transverse strain during passage of a shockwave. A 1 ns laser pulse drove an 60 kbar shock into an aluminum coated, radiation hardened, pure LiF single crystal. By diffracting a 0.

The size distributions of aerosol particles generated in N2 and O2 at ambient atmospheric pressure by repetitive excimer laser ablation of solids have been measured in quasi-steady-state from 10 nm to 1 μm diameter with a differential mobility analy

LiF (200) crystals were heated with the x rays produced when a 30 J, 0.35 μm laser pulse of 0.6 ns duration was incident on a gold‐coated titanium target at an irradiance of 2.5×1015 W cm−2. A filter arrangement allowed half of the crystal to b

The broad utility of GPS is widely recognized and appreciated. Less well known is the critical role played by the Naval Research Laboratory in its invention, concept demonstration, operational configuration, inception, and continued development. Perh

Shock waves of order 100 kbar were launched into 50‐μm‐thick single crystals of silicon (111) by irradiation with nanosecond pulses of 1.05‐μm laser light at irradiances in the region of 2×1010 W cm−2. A separate laser beam, synchronous bu

Novel X-ray sources and applications may be achieved with a combination of gateable electron micro-sources and tailored electron targets. A simple, broad area X-ray source can be constructed in a biplanar geometry, one side consisting of a low atomic

Absolute intensities of spectra in a dense-plasma-focus (DPF) source have been recorded and analyzed. This DPF source has been identified as one of the more promising sources for X-ray lithography. The source, developed by Science Research Laboratory

X-ray diffraction during transient events requires a high x-ray brightness source which is spatially collimated or spectrally concentrated, as well as synchronizable to the event. Perhaps the most demanding transient event to study is the shockwave,

X-ray diffraction from dynamically compressed solids has been an area of active research for more than half a century. As early as 1950, Schall obtained submicrosecond, single-shot x-ray diffraction patterns of single crystals under dynamic deformati
