A simple technique of the generation of high-density metal- vapor columns for x-ray capillary lasers is demonstrated. The method is based on vaporization of the electrode material in the low-pressure (P < 1 torr) capillary μs-discharge. High-density (NAl > 1017 cm -3), small-diameter (1 ÷ 6 mm), long (5 ÷ 20 cm) Al-vapor columns have been produced. The Al- vapor density along the capillary and the time-resolved spectra from Al-vapor plasmas are presented. The Al-vapor density and profile were controlled by varying the discharge parameters.

Abstract
A simple technique of the generation of high-density metal- vapor columns for x-ray capillary lasers is demonstrated. The method is based on vaporization of the electrode material in the low-pressure (P < 1 torr) capillary μs-discharge. High-density (NAl > 1017 cm -3), small-diameter (1 ÷ 6 mm), long (5 ÷ 20 cm) Al-vapor columns have been produced. The Al- vapor density along the capillary and the time-resolved spectra from Al-vapor plasmas are presented. The Al-vapor density and profile were controlled by varying the discharge parameters.File in questo prodotto:
