Titanium dioxide nanofiber-cotton targets for efficient multi-keV x-ray generation

Multi-keV x-ray generation from low-density ( 27 ± 7 mg ∕ cm 3 ) nanofiber-cotton targets composed of titanium dioxide has been investigated. The cotton targets were heated volumetrically and supersonically to a peak electron temperature of 2.3 keV , which is optimal to yield Ti K -shell x rays. Con...

Zusammenfassung:Multi-keV x-ray generation from low-density ( 27 ± 7 mg ∕ cm 3 ) nanofiber-cotton targets composed of titanium dioxide has been investigated. The cotton targets were heated volumetrically and supersonically to a peak electron temperature of 2.3 keV , which is optimal to yield Ti K -shell x rays. Considerable enhancement of conversion efficiency [ ( 3.7 ± 0.5 ) % ] from incident laser energy into Ti K -shell x rays ( 4 - 6 keV band) was attained in comparison with that [ ( 1.4 ± 0.9 ) % ] for a planar Ti-foil target.
