LeConte Hall is a building on the campus of the University of California, Berkeley. It is home to the physics department. LeConte Hall was one of the largest physics buildings in the world at the time it was opened in 1924,〔(【引用サイトリンク】url=http://www.aip.org/history/lawrence/first.htm )〕 and was also the site of the first atom collider, built by Ernest O. Lawrence in 1931.〔 The building was named in honor of the brothers Joseph and John LeConte, professors of Physics and Geology, who were respectively the first and third presidents of UC Berkeley. In 2004, LeConte Hall was named to the National Register of Historic Places.〔〔 〕 ==History== In 1924, the university opened LeConte Hall in order to accommodate an enlarged physics department, and to support the hiring of new, talented faculty. One of the newly hired faculty was Ernest Lawrence, who joined the department in 1928. Lawrence, together with students M. S. Livingston and David Sloan built an 11-inch cyclotron and installed it in room 329 LeConte. The device was the first successful, functional cyclotron and produced a current of 1.22 MeV protons. Lawrence set up the Radiation Laboratory ("Rad Lab") in the space between LeConte Hall and the Campanile. The lab was later moved up the hill and renamed Lawrence Berkeley Laboratory. Another nuclear physicist, J. Robert Oppenheimer joined the department in the summer of 1929. Oppenheimer maintained an office, together with his group of students in room 219 LeConte. In 1942, Oppenheimer was appointed head of the fast neutron research group, and in the summer of that year, he invited the leading physicists of the time to discuss the theoretical aspects of developing an atomic weapon. The physicists and Oppenheimer's students, including Hans Bethe, John Van Vleck, Felix Bloch, and others, worked in the top floor of LeConte Hall and spent a month analyzing data.〔(【引用サイトリンク】url=http://ohst.berkeley.edu/publications/oppenheimer/exhibit/chapter3.html )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LeConte Hall」の詳細全文を読む スポンサード リンク
