Bradley M. Sherrill
Bradley Marc Sherrill (* 1958 ) is an American experimental nuclear physicist who studies exotic nuclei.
Sherrill graduated from Coe College in Cedar Rapids, Iowa with a bachelor's degree in 1980 and Michigan State University , where he received his master's degree in physics in 1982 and his doctorate in 1985. As a post-doctoral student he was at GSI in Darmstadt with Ernst Roeckl and Hans Geissel . From 1986 he was at the National Superconducting Cyclotron Laboratory (NSCL) of Michigan State University in East Lansing , where he became an Assistant Professor in 1991 and later Distinguished Professor. He is director of the NSCL and scientific director of the Facility for Rare Isotope Beams, which he helped set up.
He was responsible for the design and development of the A 1200 fragment separator at the NSCL and was involved in the A 1900 fragment separator and was the project manager for the S800 spectrometer . In the plant, a heavy core such as uranium is fragmented in flight ( in flight separation ) and the fragments are separated by magnets (fragment separators).
The targeted production of exotic nuclei is important both for pure nuclear physics (for example new magic numbers , halo nuclei , fundamental symmetries) and for astrophysics (for example processes in supernovae ). While around 270 isotopes occur in nature, accelerators can theoretically generate around 7000 isotopes, but almost all of them are very unstable (exotic nuclei).
For 2018 he received the Tom W. Bonner Prize for Nuclear Physics for his scientific leadership role in the development and use of instruments and techniques for the discovery and investigation of exotic nuclei and for his leading role in clarifying the physics of particle beams with rare isotopes and the promotion of the realization of an accelerator for rare isotope radiation (Facility for Rate Isotope Beams) (laudation). In 2015 he headed the Division of Nuclear Physics (DNP) of the American Physical Society and received its Distinguished Service Award in 2014. He served on the Nuclear Physics Advisory Board for the National Science Foundation and the Department of Energy (DOE). Sherrill is a Fellow of the American Physical Society and the American Association for the Advancement of Science .
