Аннотация

Experiments were performed aimed at developing a plasma soft-x-ray source of small spatial dimensions. Radiating hot plasma was produced on compression of a metal vapor by a current pulse with amplitude Im = 215 kA and rise time Tr = 200 ns. The metal vapor jet was generated by initiating a vacuum arc discharge (Im = 8.5 kA, Tr = 6 νs) with an aluminum, tin, copper or iron cathode. Due to the small longitudinal dimension of the compressed Z-pinch, a single flash of soft x-rays was detected in the electrode gap. The least spatial dimensions of the radiating region were attained for aluminum and tin vapor pinches. When tin vapor was used, the diameter of the radiating region was 7 2 νm and its height was 17 2 νm. The x-ray pulse FWHM was 2-3 ns. The radiation power in the spectral range 1.56-1.9 keV was 10-15 MW for the aluminum vapor pinch and 5-10 MW for the tin vapor pinch.
