    摘要: Isotopic hydrogen enrichment in a soluble metal is achieved through temperature gradient effects by applying a heat source and a heat sink to two spaced regions of the metal within which isotopic hydrogen atoms are absorbed and enclosed by a diffusion-barrier material. The temperature gradient so created forces the atoms of hydrogen in the hot region to migrate into the cold region, resulting in higher isotopic hydrogen density in the cold region. Discharge of the absorbed isotopic hydrogen is prevented effectively by the diffusion-barrier material.

    摘要: Signal antennae are mounted on the casing wall between forward nose and r tail ends of an aerospace launched vehicle for radio communication through a radiation conducting sheath of plasma formed thereon by atmospheric ionization during descent of the vehicle along a non-gliding reentry path. The reentry path is maintained by vehicle guidance at a steep angle in response to data transmitted to the antennae through the radiation conducting sheath having a plasma content minimized by cooling which is thereby maintained in complete surrounding relation to the vehicle and modulated to enhance data transmission during the entire duration of vehicle descent.

    摘要: Annular arrangements of thermionic filaments adjacent opposite axial ends a chamber within which argon gas at low presure is confined, generate steady state plasma with uniformity by low energy emission of gas ionizing electrons from the filaments. The ionizing electrons and plasma generated are axially confined between grids at the axial ends of the chamber and radially confined by a low intensity magnetic field generated by an external magnetic coil.

    摘要: A weakly ionized plasma is generated by continuous high-power microwave win a dielectric cavity positioned in a slow waveguide. Contaminated air under atmospheric pressure is exposed to the plasma within the waveguide cavity for a limited saturation time controlled by inflow at a regulated flow rate. During such limited saturation time, the contaminated air is purified by sequential ionization and recombination under an electron temperature resulting in a microwave discharge plasma dominated by atomic oxygen at a relatively high saturation density level together with atomic nitrogen at a relatively low density level.

    摘要: A body of dense plasma is established within a short drift tube of a klysn amplifier between input and output resonator cavities thereof to support current modulation of microwave energy by interaction with an electron beam propagated through the drift tube. The plasma is confined to a column radially spaced from the electron beam for two-stream interaction enabling enhancement of current modulation under simultaneous high-power and high frequency operation.

    摘要: Contaminants within the gaseous emission discharged from an incinerator are eliminated during passage in parallel through reactor chambers by chemical reaction induced during exposure to plasma generated within said chambers. The plasma is generated by corona-discharge breakdown of electric fields established about electrodes within the reactor chambers upon supply thereto of electrical pulse voltage exceeding a critical field breakdown value inversely proportional to a high chamber temperature of the gaseous emission under atmospheric pressure within the reactor chambers.

    摘要: A steady-state source of neutrons is produced within an electrically grounded and temperature controlled chamber confining tritium or deuterium plasma at a predetermined density to effect implantation of ions in the surface of a palladium target rod coated with diffusion barrier material and immersed in such plasma. The rod is enriched with a high concentration of deuterium atoms after a prolonged plasma ion implantation. Collision of the deuterium atoms in the target by impinging ions of the plasma initiates fusion reactions causing emission of neutrons during negative voltage pulses applied to the rod through a high power modulator. The neutrons are so generated at a relatively high dose rate under optimized process conditions.
