Title: An x-ray technique for precision laser beam synchronization

Abstract

A new x-ray technique for recording the relative arrival times of multiple laser beams at a common target with better than {+-} 10 ps accuracy has been implemented at the Nova laser facility. 100 ps, 3{omega} Nova beam are focused to separate locations on a gold ribbon target viewed from the side. The measurement consists of using well characterized re-entrant x-ray streak cameras for 1-dimensional streaked imaging of the > 3 keV x-rays emanating from these isolated laser plasmas. After making the necessary correction for the differential laser, x-ray and electron transit times involved, timing offsets as low as {+-} 7 ps are resolved, and on subsequent shots, corrected for, verified and independently checked. This level of synchronization proved critical in meeting the power balance requirements for indirectly-driven pulse-shaped Nova implosions.
