Abstract
An ultrafast x-ray framing camera is being developed at Lawrence Livermore National Laboratory to be used as a diagnostic instrument in laser experiments. The framing camera is designed to provide temporal resolution of 50 ps and spatial resolution of 30 μ at the image plane. The unique design incorporates the 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 report on current progress in the fabrication, characterization, and integration of the various components of the instrument.
