Multi-Frame X-Ray Imaging Using a Streak Camera with a Patterned Photocathode, LAO-008-16, Year 1 of 2

Presentation describes development of a new time-resolved x-ray imaging system based on compressed ultrafast photography (CUP) to achieve multi-frame imaging for energies in the 1–10 keV range with a frame rate between 1 to 10 frames per nanosecond depending on the sweep time. A patterned gold photocathode was constructed for use with an existing Kentech x-ray streak camera. Significant work in reconstruction algorithms was performed to enable reconstructions of data that are much less sparse. These algorithms were tested with optical streak camera CUP data acquired at Livermore Operations.
