title: X-ray backlighting of imploding aluminium liners on PTS facility.
abstract: The x-ray backlighting systems, including a 1.865 keV (Si Heαline) spherically bent crystal imaging system and an ∼8.3 keV (Cu Heαline) 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 ∼7.5 MA are successfully observed using these two backlighting systems, respectively.
