Diagnostics of the soft x-ray emission in a plasma focus device

Experimental results of the soft x-ray spectra investigation; from a hot plasma produced by impulse discharge of a dense plasma focus in pure neon are presented. The spectral-energy characteristics of x-ray emission were measured in the photon energy range of (0.5-5.0) keV with the help of thin absorber filters set and silicon semiconductor p-i-n detectors-SPPD11-04. A study was made at the filling gas pressure P-Ne=(2.0-6.0) Torr and at the stored capacitor bank energy W=(15-21) kJ. High degree of monochromatization far the soft x-ray emission: (similar to 90 %) was obtained According to: the experimental data characteristic plasma electron temperature in the time duration of x-ray pulse tau(1/2)=(10-100) ns has been estimated as T-e similar to(0.2-0.3) keV. The plasma parameters obtained are compared with-the results of computer simulation of the emission process.
