Resumo

A pulsed rotating plasma device with crossed fields to 80 kV/m and 0.8 T and with discharge media of either hydrogen, helium or argon has been studied experimentally. An electron concentration of 5·1021 m−3, a rotation velocity of up to 80 km/s, heat flux to insulators up to 500 MW/m2, a generated electrical power to 60 MW, an electrical energy density to 30 kJ/m3, and a specific energy output to 3·109 J/kg have been obtained.
Proceeding from the heat transfer equation, we have derived, and experimentally confirmed, a relation between the kinetic energy of the ions and their temperature, on which the efficiency and the separation coefficient of the device depend. The calculated heat flux values agree with the experimental results. The data we have obtained are required for the development and optimization of high-energy density plasma vortex capacitors and technological plasma devices used for separation of products and isotopes.
