Abstract

Time-resolved x-ray photography at the University of Rochester's Laboratory for Laser Energetics is utilized to measure the shell trajectories during the implosion of laser fusion targets. Time-resolved measurements of the x-ray emission are made by employing an x-ray streak camera coupled to an x-ray pinhole camera. Streak records are absolutely timed to the incident laser pulse to make comparisons with one-dimensional hydrodynamics computer code simulations. For useful measurements to be made, accurate pointing of the pinhole must be achieved and maintained. We describe methods to characterize the pinhole pointing and show results obtained with this system.
