X-Ray Emission From Exploded-Wire Array on SATURN
Abstract
X-Ray spectra were collected from sodium imploded-wire emissions employing the 10 MA Saturn pulsed-power accelerator at the Sandia National Laboratories. The spectral profiles of the Na X and XI alpha resonance lines were determined with a high resolution KAP (002) spectrograph while a mica crystal spectrograph was used to acquire the entire sodium K-shell emission. The computer-processed time-integrated intensity data were interpreted by comparing with theoretically-predicted spectra. A static, collisional-radiative equilibrium model incorporating multifrequency radiation transport was used to compute the spectral intensities and line shapes. The comparison between observed and calculated opacity-broadened line profiles (especially Lyman alpha) indicates the presence of small emitting regions of high-density plasma which is also consistent with time-resolved, framing-camera X-ray pinhole images. Implications of these results for the Na-Ne photopumped x-ray laser are discussed.
