Lawrence immediately envisioned his own device that would accomplish the same acceleration in a more efficient, improved manner. Lawrence built his first model for the cyclotron out of scraps and shards of glass, with help from fellow physicist Stanley Livingston. The results of these experiments provided valuable clues about the behavior of atoms. Lawrence would receive the Nobel Prize in Physics for developing the cyclotron. New and improved versions of the device emerged quickly: in an inch cyclotron sat in the Rad Lab, in it had been replaced by a inch iteration, and by , Lawrence had created a inch machine.

As the cyclotron evolved, so did its name, which became calutron to designate its origins at the University of California. Lawrence believed his machines could separate U by electromagnetic separation, one of the four possible uranium isotope separation methods under consideration during the Manhattan Project. Although Lawrence asserted the potential of the calutron, he advised General Leslie Groves to pursue other methods separately. The model for the calutron was subsequently used at the Y plant facilities at Oak Ridge, Tennessee, for uranium enrichment.

By , Berkeley chemistry professor Emilio Segre believed that the mysterious force obtained from element 94 could substitute for U in nuclear reactions. Berkeley professor Glenn Seaborg was also conducting research on the element to identify and separate the substance.
Seaborg had produced the element neptunium, from which element 94 was produced, by bombarding uranium with neutrons. Seaborg had also managed to isolate several materials from his sample of bombarded uranium, including a piece of material that appeared to contain element Throughout January and February of the following year, Seaborg and Segre worked together along with chemistry professor Joseph Wade Kennedy to isolate and investigate the properties of element The landmark discovery fueled the hopes of Groves and other key Manhattan Project administrators and scientists, who hoped with the rise of plutonium that a new bomb could be created that would fission more successfully.
This plutonium would eventually be used in Fat Man, the plutonium bomb dropped on Nagasaki on August 9, The scientists at Berkeley first entered the war effort through the efforts of the MAUD Committee , the British group that formed to discuss the logistics of an atomic bomb program. Uranium Committee emphasizing the military possibilities of atomic energy. Frustrated, Oliphant visited Ernest Lawrence to explain the urgency of the situation.
With the help of Lawrence, Oliphant's message eventually made its way to Vannevar Bush, who had recently been named chairman of the National Defense Research Committee. Berkeley had already become the center for theoretical physics in the United States, thanks in part to the efforts of a brilliant physicist named J. Displayed here are Job Ads that match your query.
