Notes on jet-clump interaction targets (Black 1 – Black 4) for NLUF shots of 20 January 2011
Compilation of radiographs received from Robert Stamm on 21 December 2010, with approximate dimensions added.
Red lines are outline of jet-forming washer and axis of jet. Black lines and figures show approximate positions of bottom, top, and centre-of-gravity of clump of particles.
Pre-shot radiography axes are -45, 0, +45 degrees. Radiography axes in experiment are -36 and +36 degrees.
End view of target does not have sufficient dynamic range to show ball positions in pre-shot radiographs.
Slides 2 – 5 are pre-shot radiographs.Slide 6 is email from Robert Stamm.Slides 7 – 12 are target request.
The manufactured targets are a good approximation to what was requested, although the ball cluster is about 0.25 – 0.75 mm further downstream than requested.
Need decision on order of preference for these targets, and choice of backlighter times.

Hi John,
Attached are the radiographs of the “Type A” 300 um offset foam assemblies (Jet and multi-ball interaction : OMG-ASM-0164 (nominally 4 targets with approx 25 balls, set 300 um off center) :Use components C-2, C-3, C-4, C-5.
It was difficult to penetrate through the titanium and gold ablators to see the offset balls in the foam. Let me know if these are acceptable. If not, we can try a much longer exposure when we come back the week of 1/3/11 after the holiday shutdown and see if that will work.
I will be out of office 12/22 through 1/3/11.
We will send the rest with the QA report to you by ~ 1/12/11.
Thanks,
Robert Stamm
