The cosmic ray particles spread out to form a shower front. The shower front is illustrated using green dots to represent electrons and positrons, and red dots to represent muons. Yellow indicates that particles have been detected coincidentally by one of the water tank detectors. Slight differences in the detection times at the various tank positions allow scientists to determine the cosmic ray arrival direction. See the sketch of the cosmic ray creating an air shower and heading towards the detector on the previous page. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Auger-Animation/Auger-Animation.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
