Karl Berkelman
Karl Berkelman (born June 7, 1933 in Lewiston (Maine) , † February 26, 2009 in Sayre , Pennsylvania ) was an American experimental particle physicist and professor at Cornell University .
Life
Berkelman graduated from the University of Rochester with a bachelor's degree in 1955 and received a PhD in physics from Cornell University in 1959. As a post-doctoral student he was at the Italian national synchrotron laboratory in Frascati.
From 1961 he was Assistant Professor and from 1967 Professor at Cornell University.
From 1985 to 2000 he was director of the Laboratory of Nuclear Studies there, during which time he led the development of the electron-positron storage ring CESR (in operation from 1979) and the associated detector CLEO (later part of the Cornell Laboratory for Accelerator-based Sciences and Education , CLASSE). He also led the development of the CLEO 2 detector. The storage ring was at the top of the collider for ten years in terms of beam intensity. With him the physics of heavy quarks and leptons was researched. In 1995 he became Goldwin Smith Professor of Physics. In 2006 he retired, but remained active in the CLEO collaboration.
In the 1960s he was involved in fundamental experiments on the structure of the proton under Robert R. Wilson at Cornell and led a group that succeeded in measuring the size of the pi meson for the first time. In the 1970s he was engaged in experiments on inelastic scattering of electrons by protons and was involved in the further development of accelerators and detectors at Cornell (he designed the injection system for electrons from the synchrotron into the storage ring and wrote programs for CLEO to reconstruct the particle trajectories ).
In 2004, he published his experience in running CESR and the history of particle accelerators at Cornell University in a book.
In 1967/68, 1981/82, 1991/92 and 2000/2001 he was at CERN and 1974/75 at DESY .
He dealt with experiments on electron-positron colliders, high-energy scattering of electrons, meson photoproduction and the phenomenology of elementary particle interactions at high energies.
He was a Fellow of the American Physical Society and a Loeb Lecturer .
He was married and had three sons.
