The first experiments on the national ignition facility

“…The beam synchronization was set to 6 ps rms by comparing the timing of streaked 2 keV 1D images [26] of four separate 200 ps laser-plasmas created by the four beams impinging on a gold disk. The pointing accuracy for the pulsed beams was verified to be better than 75 µm rms from SXI images of the four laser-plasmas at best focus (< 200 µm spot size) impinging on a gold disk equipped with spatial fiducials.…”

“…The signal that is recorded from a single burst of x-rays appears as a cumed band on the film [3]. The curvature of the data is a result of the three components that add to give the overall curvature.…”
