George Kenneth Green

George Kenneth Green, called Ken Green, (* 1911, † August 1977) was an American physicist who worked on particle accelerators.

Green studied at the University of California, Berkeley, where he belonged to the group of Ernest Orlando Lawrence. After the Second World War he was at Brookhaven National Laboratory ( BNL ) in M. Stanley Livingston, who there built the cosmotron. Green began after the discovery of the strong focus of Livingston, Ernest Courant and Snyder this idea ( in competition with the Europeans at CERN ) at BNL in the construction of the alternating gradient (AG) synchrotron to which was commissioned in 1960 and reached 33 GeV. He collaborated with John Blewett. In the 1960s, there were conflicts within the BNL informed about which research direction between experimental particle physicists ( as Maurice Goldhaber, director of the laboratories) and accelerator developers. The next larger machine ( in the 200 GeV range) after the AGS should be built according to internal arrangements of Berkeley ( and was at the end realized in the Fermilab ), and Green wanted to focus the research on the superconducting magnets and the development of a collider for the next- generation of accelerators his opponents wanted the research funds rather get stuck in ongoing experiments at accelerators. Green was therefore replaced in 1969 as director of the AGS. Green then devoted himself alternative ( solar ) energy supply for the BNL and the project study for the National Synchrotron Light Source ( NSLS ), which was built in 1978 and its rings from 1982 to 1984 went into operation. With Renate Chasman he developed the Chasman -Green lattice later much used as a building block for synchrotron sources ( Chasman Green Lattice ). Even in the development of the ISABELLE accelerator at BNL, he was involved in, the next large accelerator project after the AGS of BNL under the direction of Green's successor Blewett.
