The first X-ray backlighting of Z-pinched aluminium liner experiment on PTS facility

The first X-ray backlighting of Z-pinched aluminium liner with sinusoidal perturbations experiment was carried out on PTS facility. A kilo-joule laser (1053 nm, 1 kJ, 1 ns) was used to drive the solid target to produce X-rays and the development of the instability of the Z-pinched aluminium liner outer edge, under a driver current of 7.5 MA, was successfully observed by using the monochromatic X-ray backlighting based on spherical-bent crystal and the direct point shadow radiography, respectively. This experiment confirmed the capability of X-ray backlighting on the PTS facility by union of the kilo-joule laser and it provided the foundation for the subsequent researching of the fine Z-pinch physics.
