Determination of the parameters of a plasma JET generated by a capillary discharge

A pulsed capillary discharge has been the subject of various experimental and theoretical studies. A jet of copperhydrogen plasma with a cylindrical symmetry has been developed as a light source for spectroscopic measurements. The electron density of the plasma was obtained by using the Hβ spectral line of the hydrogen component plasma. The electron temperature was determined by means of the Boltzmann method applied to the copper profiles emitted by the plasma jet. The copper and hydrogen lines were broadened principally by the Stark effect. The electron density of the plasma was found to be about 2×1017 cm–3 and the electron temperature about 20000K.

A fusion-fission hybrid reactor driven by high-density pinch plasmas

A conceptual design for a 200 MW hybrid fusion-fission reactor to be used as a heat source for district heating has been developed. The fission, heat-generating blanket is based on the CANDU reactor technology, while the fusion fast neutrons are provided by a high-density, pinch plasma. The basic assumption regarding the fusion neutron source is that in a pinch plasma (high-density Z-pinch and plasma focus configurations have been considered) a fusion power level of 10 MW can be achieved. An outstanding feature of the design is that no active components are necessary within the reactor containment area, all the hybrid system control being ensured by the fusion component of the reactor.
