Fig. 1. Experimental layout for the Orion POLAR campaign.

Fig. 2. A CAD representation of the target sliced through the centreline (annotations are described in the text above).

Fig. 3. Shows a 3D CAD cut away of the target and indicates the positions of the pusher foil position and also shows the foam insert at the bottom of the tube.

Fig. 4. A fully processed Brominated plastic disk showing internal structure (dark areas are the un-melted material).

Fig. 5. A low-density sample placed at the end of the PI tube next to the quartz obstacle.

Fig. 6. Images of the POLAR target from the obstacle side (left) the Au/CH pusher (right).

Fig. 7. A side view of the foam inside the tube with the grid above.

Fig. 8. The backlighter target design.

Fig. 9. The fully assembled backlighter target.

Fig. 10. Sample backlighter images showing: (a) the PI tube with the quartz/steel obstacle at the top, the diagnostic slits cut in to the tube and the gold resolution grid attached to the target and (b) the PI tube with the quartz/steel obstacle at the top and a low-density foam insert below the stop.
