Abstract:
Experiments with electric discharges across hollow gaseous envelopes have been carried out on a microsecond plasma generator of x radiation (200 kA, 40 kV, 1.5 μs, Ne–Ar mixture). The diagnostic complex made it possible to carry out time- and space-resolved observations in the visible range by means of streak and framing cameras. In the vacuum-UV range, a spectrograph with a transparent grating and a vacuum x-ray diode were used. In the soft x-ray range, a crystal spectrograph with convex and spherically bent crystals, a crystal x-ray microscope, pinhole cameras, and p-i-n diodes were used. The spectral range 0.3–1.5 nm contains lines of He- and H-like Ne and of He-like Ar. These ions are used for x-ray-spectral estimates of the electron temperatures and the densities of the plasma of the hot spots. These estimates lie in the ranges 1–1.3 keV and (0.5–1) · 1022 cm–3. At the optimum nozzle diameter in terms of the x-ray yield, a kink instability and the formation of hot spots are observed simultaneously. Suppressing the kink instability increases the radiation yield. Emission from the plasma column in Kα lines of argon has been observed.
