Harvard and M.I.T. announced this week that the Atomic Energy Commission is treating them jointly to a 6 billion-volt electron synchrotron, which will be built in Cambridge. Cost: $6,500,000. Its electrons will be steered around a circular vacuum chamber 236 ft. in diameter by 48 powerful magnets, each 11 ft. long, and they will be nudged to enormous speed by 16 radio-frequency circuits, each with the power of a full-scale television transmitter...
...first official joint action by the two institutions since the war came last year when they collaborated on a plan for constructing a linear electron accelerator. Their plan has been entered in an A.E.C. contest, and if they win, Harvard and M.I.T. will construct and operate the accelerator jointly...
...accelerator will be capable of producing energies up to 22 billion electron-volts and will cost approximately $20,000,000. Preliminary construction has been going on for two years, and the project should be completed by 1959, according to Brooks...
...alien particles is annihilated. The antiproton (P¯ ) enters from the left. It is moving fast at first, but gradually slows down and merges with the nucleus of some unfortunate atom. There it combines with a proton or neutron, and both particles vanish, turning into 1,876 million electron volts of energy. The resulting explosion-extremely violent on the atomic scale-drives off fast-moving fragments that trace the lines of the star...
...energy carried away by each particle can be measured by examining closely the track that it made. In this star, the total energy of the visible particles alone adds up to 1,230 million electron volts. Since only 938 million electron volts can be released by turning a single particle into energy, more than one particle must have been annihilated. Physicists consider this an elegant proof that antiprotons really perform as theorists many years ago predicted that they would...
