ABSTRACT
We describe the development and characterization of an ultrafast x-ray framing camera capable of recording images with a temporal resolution of 50 ps and spatial resolution of 22 μm at the image plane. The unique design incorporates an x-ray photocathode directly into a suspended-strip transmission line. The photocathode is gated using a high-voltage (-5-kV) pulse of short duration generated with a photoconductive switch. The photoelectrons are extracted through an unbiased microchannel plate and are directly detected with a charge-coupled device in the electron-bombardment mode. We discuss applications of the camera to investigate the dynamics of laser-produced plasmas.
