...years ago, at Cambridge University, Physicists John D. Cockcroft and Ernest T. S. Walton shot hydrogen nuclei (protons) from a primitive high-voltage machine at a lithium target. A few of the protons hit lithium nuclei. The product of each such reaction: two atoms of helium and 17.3 million electron-volts of energy...
...University of California scientists who designed and built the bevatron are gradually stepping up its energy, starting only small groups of protons around the magnetic race track, but already their energy at the end of their run is 4.7 billion electron-volts. This is twice the energy of the second largest accelerator, the cosmotron at Brookhaven National Laboratory, Long Island. It is the energy of middle sized cosmic-ray particles, which have been accelerated, perhaps for billions of years, by unknown forces in space. Each proton at the end of its journey has a mass six times as great...
...From bev, scientists' shorthand for billion electron-volts. * By the Einstein principle that mass increases with speed...
...heavy barrage of tear gas shells finally quelled the Nationalists. Campos was carried from the building, his head and feet swaddled in towels, mumbling "Estoy asfixiado" (I am chocked). The towels were his protection from the "electron rays" he has recently protested the United States is directing against...
...days to six months.* Said Health Commissioner Bruce Underwood: "This legislation makes it a crime to spread tuberculosis." ¶General Electric's X-ray department in Milwaukee announced this week that, in cooperation with both government and private organizations, it would produce a new 6,000,000-volt electron gun for treating cancer. The gun was designed by Professor Edward L. Ginzton, head of Stanford's Microwave Laboratory, and Radiologist Henry S. Kaplan of Stanford Medical School. Treating cancer with X-rays has always been a tricky business, due to the danger of radiation injuries to healthy tissue...
