Fritz Goro—Time & Life Pictures/Getty Images by [Ben Cosgrove](https://time.com/author/ben-cosgrove/) ## Ben Cosgrove Mar 13, 2013 9:35 PM UTC In the world of technology, what’s cutting-edge in the morning is often on the scrap-heap by noon. But some machines are so revolutionary, so innovative—so _cool_—that even years after they’ve been largely outpaced or even replaced by other, more efficient or more powerful devices, they can still amaze. One such marvel is the early cyclotron: a huge, proto-atom smasher that led to, among other things, key breakthroughs in the study of subatomic particles and, in a sense, to the later [Atomic Age](http://www.npr.org/blogs/pictureshow/2011/03/17/134604352/images-of-the-atomic-age) itself. Here, LIFE.com celebrates the remarkable instrument, and the minds that conceived, refined and worked wonders with it when it was still at-once the sharpest and bulkiest of edgy tech. [\[MORE: A 2007 requiem for Columbia University’s famed cyclotron in the _Times_\]](http://www.nytimes.com/2007/12/20/nyregion/20atom.html) The way most cyclotrons work is, at heart, almost rudimentary: particles sped up by the enormous device’s transmitter and magnet form a beam of energy. “When this beam is directed against a metal target,” LIFE explained to its readers in a February 1940 issue, “enough of the particles hit the nuclei in the metal to cause atomic explosions, making them give off neutrons or other radiations. When other substances, in turn, are bombarded with neutrons, new substances are formed, which explode with radioactive violence. These artificially radioactive substances are of great use in biological research”—particularly, the article noted, the battle against cancer. Cyclotrons were so much a part of the national conversation in the late 1940s, in fact, that in an advertisement in a 1948 issue of LIFE, Shell Oil not only touted its products’ use in Columbia’s Nevis Lab cyclotron, located 20 miles north of Manhattan in Irvington, N.Y., but actually took the valuable ad space to discuss how the machine worked: --- > “” --- The huge Nevis Lab cyclotron, LIFE pointed out, employing an image that would resonate with its readers a few short years after the end of World War II, contained “as much steel as a destroyer.” The cost of the machine? Two million dollars. Million. With an M. ---  Model of the large magnet for University of Chicago's cyclotron, 1948.

Fritz Goro—Time & Life Pictures/Getty Images  A sheet of metal resists a man's efforts to pull it from between the Columbia cyclotron's two magnetized poles. "After the christening," LIFE magazine reported of the ceremony around the new cyclotron, "the magnet was turned on and, like kids exploring the possibilities of a new toy, physicists swarmed around to see how hard it could pull ..."

"For the rest of the afternoon," LIFE wrote of the fun and games at the cyclotron's christening party, "science stood still. Not until day's end were the scientists, thoroughly exhausted, willing to return once more to their serious occupation of tearing atoms apart."

In March of that year, TIME reported: "The University of California admitted last week that it had created the first man-made meson ... with its 4,000-ton cyclotron. \[Mesons are unstable, short-lived subatomic particles that last for, perhaps, a few hundred-millionths of a second.\] The news caused a sizable flurry throughout the world of physics — for mesons are closely connected with the unknown force that holds matter together."
