Berkeley Lab's Washington, DC Projects Office provides a presence for the Lab near the US Department of Energy Headquarters. Major projects in the DC Office support the Environmental Energy Technologies Division's capabilities and effectiveness in providing high-quality technical research and policy analysis to the Department of Energy and other governmental and non-governmental sponsors. The DC Office works closely with Washington-based research sponsors to help Division researchers understand sponsors' needs and to design and conduct projects that best meet those needs. The DC Office provides an additional outlet for transmitting the results of LBL research and analysis. In addition, the office coordinates research, analysis, and technology-transfer activities with the Washington offices of other National Laboratories.

82. A Science Odyssey: People And Discoveries: Lawrence Invents The Cyclotron When ernest orlando lawrence (19011958) got his PhD in physics, the hottest topicwas bombarding the atom s nucleus to see what new particles it might produce http://www.pbs.org/wgbh/aso/databank/entries/dp31cy.html

Lawrence invents the cyclotron Photo: Four-inch copper-encased cyclotron, one of Ernest Lawrence's ealiest models When Ernest Orlando Lawrence (1901-1958) got his PhD in physics, the hottest topic was bombarding the atom's nucleus to see what new particles it might produce. Ernest Rutherford had only recently shown that striking the atom of one element could make it emit electrons and turn into a different element. Lawrence joined the physics faculty of the University of California (Berkeley) in 1928 and got intrigued with this new physics. So far, people had used alpha particles (the product of natural radioactivity) and protons (hydrogen atoms, containing a positive charge of 1) to bombard other atoms. But they had about exhausted that field of research. To learn more, they needed an artificial way to accelerate these particles to greater energy. Several accelerators were invented to give the bombarding particle a huge "kick" of electric potential. But it seemed that you'd need a kick of about 1 million volts to get the required acceleration, and making a machine to withstand that power was nearly impossible. Around this time, Lawrence happened to read a German paper describing a linear accelerator that boosted a particle's energy in steps using alternating electric fields. This did increase the particle's speed but to really get it up to the desired energy, the accelerator would have had to be impractically long. Lawrence knew that a magnetic field would deflect the charged particles into a curved path. By making the particles go in a spiral, he could boost their energy bit by bit each time they circled an electrode. The circular machine could fit in one room. The particles would spiral outward as they gained more energy, and when they were moving fast enough, they'd shoot out of the device with amazing force into a collector.

American physicist Ernest Lawrence received the 1939 Nobel Prize for inventing the cyclotron. Credit went to Lawrence, but Szilard invented it first. Szilard filed a German patent application on the cyclotron on January 5, 1929. Lawrence conceived the idea independently several months later. Lawrence's American patent application was not filed until January 26, 1932. regular page. UP to Leo Szilard Home Page Gene Dannen / danneng@peak.org
