...John Douglas Cockcroft, director of the Atomic Energy Research Establishment at Harwell, England, outlined a program for nuclear power development that will halve the cost of electricity in Britain within the next five years. He delivered the first Morris Loeb Lecture at Burr Hall last night...
...John Douglas Cockcroft, director of the Atomic Energy Research Establishment at Harwell, will give the Morris Loeb Lecture on "The Course of Development of Nuclear Power" tonight at 8:30 in Allston Burr Hall B. He will be presented by President Pusey...
Consolation for Physicists. At the Oxford meeting of the British Association for the Advancement of Science, Nobel Prizewinner Sir John Cockcroft announced a bit of long-range good news. He was sure, said Sir John, that long before the world exhausts its supply of uranium fuel, the energy of "the fusion of light elements (as in the hydrogen bomb) can be turned from destructive to peaceful uses. If this is true, the human' race need not worry about its energy supply for a very long time...
...Fusion" of light elements, on which the hydrogen bomb depends, is the senior source of nuclear energy. More than 20 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...
Except for such demonstrations as the 1932 Cockcroft-Walton experiment, the only way to get a fusion reaction is to raise the temperature. The hotter a material gets, the faster its atoms move. If it gets hot enough, they may hit one another so hard that they combine into larger atoms, yielding the energy of fusion...
