Thermo-nuclear fusion may be the key to a high Isp, high specific power propulsion system. In a fusion system energy is liberated within, and imparted directly to, the propellant. In principle, this can overcome the performance limitations inherent in systems that require thermal power transfer across a material boundary, and/or multiple power conversion stages (NTR, NEP). A thermo-nuclear ...

Lithium niobate is praised as silicon in nonlinear optics for its wide usage both in fundamental science and applications in optics. But its photorefractive effect hinders it from more extensive application in optics. The deadlock has been broken by doping some metallic elements such as magnesium into the congruent lithium niobate crystal for its high ...
The theoretical background and considerations leading to the choice of experimental methods for an investigation of the kinetics of dissolution and the solubility of structural metals in lithium are presented. The selection of methods, development of expenimental techniques, and design, construction, installation, and testing of equipment are discussed. The apparatus ...
Lithium niobate has been for many years the workhorse of nonlinear optics technology and is currently in wide use for frequency up conversion acousto-optic devices and optical switching. More recently, potassium niobate has attracted attention as a ring r...

A charge-exchange cell based on pulsed-laser ablation has been developed and applied to collinear resonance ionization spectroscopy. A fast lithium ion beam has been neutralized in the charge-exchange cell and resonance ionization spectra of the 2s2S1/2- 2p2P01/2.3/2 transitions of lithium have been successfully observed. The ...
Studies of ablatively driven, relativistic electron beam target implosions have been made with a two-frame, 3-ns exposure flash, x-radiography system. The spherical targets were filled with 200 atm of deuterium gas and had a copper shell thickness greater than the electron range. In addition, the copper shell was lined with a thin gold layer which permitted direct radiographic ...
