Title: 22 December 2011 1 22 December 2011 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. 2 Black_1_RF101018-3(C-2) 2X -45Deg.jpg Black_1_RF101018-3(C-2) 2X 0Deg.jpg Black_1_RF101018-3(C-2) 2X 45Deg.jpg Black_1_RF101018-3(C-2) 4X Sphere.jpg Black_1_RF101018-3(C-2) 4X Hohlraum.jpg 3 Black_2_RF101022-5(C-4) 2X 0Deg.jpg Black_2_RF101022-5(C-4) 2X -45Deg.jpg Black_2_RF101022-5(C-4) 2X 45Deg.jpg Black_2_RF101022-5(C-4) 4X Hohlraum.jpg Black_2_RF101022-5(C-4) 4X Sphere.jpg 4 Black_3_RF101101-4(C-5) 2X -45Deg.jpg Black_3_RF101101-4(C-5) 2X 0Deg.jpg Black_3_RF101101-4(C-5) 2X 45Deg.jpg Black_3_RF101101-4(C-5) 4X Hohlraum.jpg Black_3_RF101101-4(C-5) 4X -Sphere.jpg 5 Black_4_RF101018-4(C-3) 2X -45Deg.jpg Black_4_RF101018-4(C-3) 2X 0Deg.jpg Black_4_RF101018-4(C-3) 2X 45Deg.jpg Black_4_RF101018-4(C-3) 4X Sphere.jpg Black_4_RF101018-4(C-3) 4X Hohlraum.jpg Black_4_RF101018-4(C-3) 4X -Sphere85keV.jpg 6 Email from Robert Stamm, 21 December 2010 Stamm, Robert M rmstamm_at_sandia.gov 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.
