Each of the 3,000-gallon tanks is a particle detector for capturing cosmic rays. The Auger Observatory uses both water tanks and optical detectors to measure the cosmic ray air showers. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/FNAL-Auger-Detector/FNAL-Auger-Detector.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/MIT-Clark-Kraushaar-1956/MIT-Clark-Kraushaar-1956.dc.xml Professors William Kraushaar and George Clark close the air-tight cover on the balloon gondola that carried the second of their two (unsuccessful) balloon experiments in search for high-energy cosmic gamma rays. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/MIT-Clark-Kraushaar-1956/MIT-Clark-Kraushaar-1956.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/MIT-Rossi-BBR-45/MIT-Rossi-BBR-45.dc.xml Professor Bruno Rossi supervises as a student assembles equipment for a cosmic ray balloon experiment in 1948. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/MIT-Rossi-BBR-45/MIT-Rossi-BBR-45.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/SSP-1945-winners/SSP-1945-winners.dc.xml Winners of the 1945 Westinghouse Science Talent Search assemble with Vice-President Harry S. Truman. George Clark was among the top ten finalists who were selected as winners. He stands 6th from the left in the back row. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/SSP-1945-winners/SSP-1945-winners.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/explorer-11_grbd/explorer-11_grbd.dc.xml Kraushaar and Clark’s detector for Explorer 11 was designed to detect gamma rays above 50 MeV. The image on the left shows the detector. It measured 20 inches high, 10 inches in diameter, and weighed about 30 pounds. The image on the right is a diagram of the detector, which consisted of a sandwich crystal scintillator and a Lucite Cherenkov counter, surrounded by a plastic anticoincidence scintillator. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/explorer-11_grbd/explorer-11_grbd.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
