Nicholas P. Samios

from Wikipedia, the free encyclopedia

Nicholas Peter Samios (born March 15, 1932 in New York City ) is a Greek-American experimental elementary particle physicist .

Samios (who grew up in Livadi on the island of Kythira in Greece) studied physics at Columbia University , where he received his bachelor's degree in 1953 and his doctorate there in 1957. Then he was an instructor there and from 1959 at the Brookhaven National Laboratory (BNL), where he was already a summer break student in 1952 and was a senior physicist from 1962. There he was head of various departments and from 1982 to 1997 director of the laboratory. From 1997 he was Distinguished Senior Scientist at the BNL, from 1998 Deputy Director and from 2003 Director of the RIKEN BNL Research Center (RBRC). 1970 to 1995 he was an adjunct professor at Columbia University.

During his time as laboratory director, the RHIC was built at the BNL (it went into operation in 2000), a heavy ion accelerator with which, among other things, the formation of quark-gluon plasma was investigated.

In 1993 he and Robert Brian Palmer and Ralph P. Shutt received the Panofsky Prize for the discovery of the Omega Minus particle in 1964, an important confirmation of the quark model (it consists of three strange quarks and was predicted in 1961). This was achieved with the largest particle detector at the time, the 80 inch bubble chamber of the BNL at the AGS synchrotron . He was also involved in experiments on parity violation in Hyperon decays in the 1950s .

For many years he was also involved in neutrino scattering experiments at the BNL and Fermilab , which among other things led to the discovery of the charm lambda particle, the first discovered baryon with charm quarks . In addition, he carried out early measurements on the cross-section of elastic electron-neutrino scattering and achieved experimental limits for neutrino oscillations.

In 1980 he received the Ernest Orlando Lawrence Prize and the Physics and Mathematics Prize from the New York Academy of Sciences. In 2009 he received the Gian-Carlo Wick gold medal. In 2001 he received the Bruno Pontecorvo Prize of the JINR in Dubna.

He is a Fellow of the American Physical Society , the National Academy of Sciences , the American Academy of Arts and Sciences , the American Association for the Advancement of Science and a corresponding member of the Akademia Athenon.

He has been married to Mary Linakis since 1958 and has two sons and a daughter.
