  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.

  6. Email from Robert Stamm, 21 December 2010 Stamm, Robert M [rmstamm@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. Thanks, Robert Stamm Schafer Corporation at Sandia National Labs 1515 Eubank SE RM.1241 BLDG.962 MS1196 Albuquerque, NM 87123 Desk 505 284 8385 Pager 505 951 5605 FAX 505 844 0573 http://www.schafercorp.com/Company/sl/icf.htm
