摘要：
The x-ray backlighting systems, including a 1.865 keV (Si Hea line) spherically bent crystal imaging system and an similar to 8.3 keV (Cu Hea line) point-projection imaging system, newly fielded on the Primary Test Stand facility are introduced and its preliminary experimental results in radiography of the aluminium (Al) liners with seeded sinusoidal perturbations are presented. The x-ray backlighter source is created using a 1 TW, 1 kJ Nd: glass high power laser, kilo-joule laser system, recently constructed at China Academy of Engineering Physics. The ablation melt and instability of the imploding Al liner outer edge under the driving current of similar to 7.5 MA are successfully observed using these two backlighting systems, respectively.
