The CALorimetric Electron Telescope (CALET), launched from the Tanegashima Space Center off the southern coast of Japan to the International Space Station in August 2015, has now detected over a hundred million cosmic ray events above 10 GeV. The 1400 lb CALET experiment is the first instrument specifically designed to identify electrons at energies above 10^12 electron volts, and will spend the next 2-5 years measuring very high energy cosmic ray electrons, nuclei, and gamma rays. At LSU, John Wefel, Mike Cherry, Greg Guzik, Amir Javaid, Nick Cannady, Bethany Broekhoven, Doug Granger, Michael Stewart, and a team of undergraduates are working with collaborators at over 30 institutions in Japan, Italy, and the US to analyze the CALET data.
