Rope tricks[edit]

Tumbler snapper rope tricks

I'm taking a chance on this one, I know. This is an image of a nuclear detonation at 1ms after zero time showing "rope tricks". Exposure is 3 µs. I know the image suffers from moire due to effects of scanning a halftone image (and I would be grateful if someone can clean it up), but I feel the subject matter is so unique and fascinating it might be overlooked. This is probably the highest quality image available of this phenomenon.

    • If you can scan the image at a higher resolution and upload it as a low-compression jpg or no-compression png, I can probably remove the moire patterns. --brian0918™ 15:22, 8 Apr 2005 (UTC)

    • I'm ....pretty sure ...I nominated but I'll take what I can get :o) !!--Deglr6328 01:00, 9 Apr 2005 (UTC)
  • Support I have always found this microsecond phenomenon fascinating Denni 02:30, 2005 Apr 9 (UTC)
  • Support, though if a cleaner image can be developed, without the moiré pattern, I will be even more enthusiastic. I've had a quick look at Michael Light's 100 Suns, published in 2003, and agree this photo illustrates rope tricks and the "mottling" effect superbly. The Tumbler-Snapper test series comprised six detonations beginning in April 1952 at the Nevada Test Site. Sandover 02:34, 9 Apr 2005 (UTC)

      • Info from http://www.radiochemistry.org/history/nuke_tests/tumbler_snapper/ added to image info to support PD attribution as US government photo- Bevo 14:35, 26 Apr 2005 (UTC)
      • I don't know how to conclusively PROVE that this image was taken by a govt. employee but I have seen it published in several places with statements that it is a gov. image. Really, I don't know how it could be anything else. The image was taken at some time in 1952. I am unaware of the DOD ever allowing ANY private individual or organization to image bomb tests with ultrafast rapatronic equipment, let alone allowing them to take such images so early on in the testing in the early '50s. It would be a hige security risk. I am 99.999% certain this is a gov. work and in the public domain. :)--Deglr6328 16:41, 26 Apr 2005 (UTC)
        • Addendum. Here is a statemtnt by Michael Light, the author of 100 suns, which gives insight to where he obtained the rapatronic images for his book. "At the still picture branch of the United States National Archives at College Park, Maryland, head archivist Kate Flaherty was unfailingly helpful during all aspects of research at that great institution, as were her staff members Theresa Roy and Sharon Culley. Roger Meade, chief archivist at the Los Alamos National Laboratory in New Mexico, went above the call of duty to make material available and help identify some of its more arcane aspects. At Lawrence Livermore National Laboratory in California, archivists Steve Wofford, Beverly Bull and Maxine Trost helped with image research. Nick Broderick, classification analyst at Lawrence Livermore, kindly provided final identification of notoriously difficult to attribute ultra-high-speed Rapatronic images made by E.G.&G. Thanks as well to filmmaker Peter Kuran for additional identification help with Rapatronic images." --Deglr6328 16:54, 26 Apr 2005 (UTC)
