Search for the first beam from the proton linear accelerator, October 16, 1947. Alvarez's 8:30 p.m. blackboard calculation proving that geometry must be changed and that the machine would not work , with an added note that at 2:40 a.m., six hours later, they achieved the beam. Luis Walter Alvarez (June 13, 1911 - September 1, 1988) was an American experimental physicist, inventor, and professor. In 1936, he went to work for Ernest Lawrence at the Radiation Laboratory at the University of California, Berkeley, where he devised a set of experiments to observe K-electron capture in radioactive nuclei, predicted by the beta decay theory but never observed, In 1940 he joined the MIT Radiation Laboratory, where he contributed to a number of WWII radar projects. He spent a few months at the University of Chicago working on nuclear reactors for Enrico Fermi before coming to Los Alamos to work for Robert Oppenheimer on the Manhattan project. After the war |
