Spectroscopically pure metal vapor source for highly charged ion spectroscopy and capillary discharge soft x-ray lasers.

We describe a compact, pulsed metal vapor source used for the production of dense plasma columns of interest for both soft x-ray laser research and spectroscopy of highly ionized plasmas. The source generates spectroscopically pure cadmium vapor jets in a room-temperature environment by rapidly heating an electrode with a capacitive discharge. In the… (More)
