Abstract :
Summary form only given. Saturn is uniquely suited to studying the production of warm (>5-keV) X-rays because of its ability to accelerate large (≈1-mg) masses of mid-Z elements to implosion velocities near 75 cm/μs (200 keV/ion for copper). Copper wire array experiments have produced 2.5 kJ of copper K-shell radiation near 8 keV. The copper wire arrays used for the Saturn experiments are 2 m long and have array diameters between 1.0 and 2.5 cm. Between 8 and 24 wires are loaded in the array for a shot. The wire sizes are 20-50 μm in diameter. Absolute yield and power measurements have been made with resistive bolometers and filtered photoconducting detectors: spectra have been taken with a time-integrated LiF curved-crystal spectrograph, and pinch images have been obtained with a 12-frame time resolved X-ray pinhole camera
