Radiating heterogeneous Z-pinch 2-D compression dynamics

The constriction development dynamics in dense heterogeneous profiled Z-pinches was studied on an 8-module powerful current generator, the S-300 at current up to I =3 MA with a rise time τ=70 ns. The Z-pinch energy concentration effect was provided by using axially — inhomogeneous loads, of 10 mm in height, consisted of two identical axially placed cylinders, with cylindrical insertion between them, but which had lower linear mass. For plasma formation the agar-agar foam with 1⋎100 mg/cm 3 density was used and which was added by radiating mixture (Cu, Cl, K) and deuterated substance (CD 2 ). For plasma parameter diagnostics and X-ray and neutron radiation measurements the following set of diagnosties: X-ray spectroscopy of highly ionized species of ions in the quanta energy range of 1⋎10 keV, integral and very short time frame and streak camera photography in X-ray and optical spectral ranges, neutron integral and time of flight measurements, X-ray radiation registration in the range of 0.4⋎100 keV, and laser probing was used. The impact of radiation cooling on 2-D plasma compression dynamics was studied.
