X pinch X-ray radiation above 8 keV for application to high-resolution radiography of biological specimens

The X pinch is a dense plasma X-ray source that is known to emit subnanosecond bursts of X-rays in the 2.5-8 keV energy range from a very small (/spl sim/1 /spl mu/m) source commonly referred to as a micropinch. As such, it has been successfully used as a point source for X-ray radiographic imaging of small biological samples with spatial resolution as good as 1-2 /spl mu/m. Recent experiments sho...
