X-ray emission efficiency of imploding aluminum wire plasmas

X-rays plasmas have been created by imploding wire arrays. They were driven by SIDONIX I prime pulse generator (peak power 0.5 TW, transmission line impedance 0.75 Ω, diode inductance 25 nH). Photon pulses were observed using XRD diodes, PIN diodes, a bolometer, an X-ray pinhole camera, and a convex curved crystal spectrograph. Emission efficiency and spectroscopic results are presented (an electron temperature on the order of 0.5 keV with electron density in the 10²⁰ cm⁻³ range in the hottest regions has been recorded). Attractive results were obtained by means of a l-D MHD code. These results have induced preliminary study of the implosion behaviour when a thin glass tube is introduced on the array´s axis. Pinhole photographs show intense external and internal emitting regions.
