TURBULENT MODIFICATION AND THE TRANSPORT-PROPERTIES OF PLASMA-DYNAMICDISCHARGES IN THE VACUUM ULTRAVIOLET

A method is proposed for absolute measurement of high-power (> 10(6) W /cm2) fluxes of vacuum ultraviolet radiation (hv almost-equal-to 10-10 0 eV) based on determining the speed of equilibrium ionization waves i n a mixture of gases. It is confirmed directly that turbulent modifica tion of the plasma-gas boundary greatly eases the escape of vacuum ult raviolet radiation from the plasma. The measured power of the radiatio n fluxes from open plasma-dynamic magnetoplasma compressor discharges with moderate input energies (< 10 kJ) is as high as 10(7) W/cm2, whic h is comparable to the fluxes obtained in explosion-driven experiments .
