Heavy atoms like uranium had been chipped before, but not cracked in two. Moreover, the most effective agents for splitting or "fission" of uranium were "slow" neutrons with initial energies of only a fraction of one electron-volt, so that the energy profit from one fission was enormous...
...world's biggest, most powerful. Last week he gave a progress report on this monster in operation. With a power input of only 50 kilowatts (more than enough to run a good-sized radio station), he and his crew have obtained beams of 16-million-volt heavy hydrogen particles and 32-million-volt helium particles. With the 32-million-volt beam, new radioactive substances throwing off electrified helium gas have been discovered. The machine has performed so well that Dr. Lawrence now wants a bigger one. He considers it entirely feasible to build a 2,000-ton cyclotron - costing...
Every now & then some pseudo-scientific jack-in-the-box pops up with an alleged death ray. Nearest approach to a real death ray is the 19-million-volt stream of subatomic particles produced at the University of California by Ernest Orlando Lawrence's giant new cyclotron. This 225-ton machine, whose operators shield themselves by water-tank barricades, can kill white mice and destroy cancer cells at popgun range. Installed in a front-line trench it would have less effect on an enemy soldier at 50 feet than one well-aimed rifle bullet...
...tuberculosis bacillus. Dr. White announced that a grant had been made to study the bacillus under the new world's biggest "cyclotron" or atom-smashing machine at the University of California, which weighs 225 tons and has just produced a record-breaking beam of 19,000,000-volt particles. By stuffing the bacillus with radioactive phosphorus produced in cyclotron bombardments, the California researchers will ry to make it give off a continuing stream of telltale emanations. Then, after injection into laboratory animals, the emanating germ's first furtive fortnight may be observed...
There are some 3,000,000 battery-run radio sets in the U. S. today, most of them operating on 2-volt tubes designed in 1930 to operate on heavy-duty, "air cell" batteries. Key to the 1938-39 portable is a low-drain, 1.4-volt tube developed last year. This tube, requiring slightly less "A" voltage and only 90 (instead of 135) volts for the "B" circuit, uses about one-third as much current as the 2-volt tube...
