John M. "Jack" Carpenter (June 20, 1935 - March 10, 2020) was an American nuclear engineer known as the originator of the technique for utilizing accelerator-induced intense pulses of neutrons for research and developing the first spallation slow neutron source based on a proton synchrotron, the Intense Pulsed Neutron Source (IPNS). He died on 10 March 2020.[1][2][3]
Following completion of his Ph.D., Carpenter took a Post-Doctoral Fellowship at the University of Michigan Institute for Science and Technology in Ann Arbor, Michigan, from 1963 to 1964.[4][7] In 1964 he joined the UM faculty as an assistant professor in the Department of Nuclear Engineering; he was promoted to full professor in 1973.[4][7]
During his career, Carpenter has held a number of term appointments at public and private institutions, including Visiting Scientist at Phillips Petroleum Company, Nuclear Technology Branch, Idaho Falls, Idaho, Fall 1965; Argonne National Laboratory, Solid State Science Division, 1971–1972, 1973; Los Alamos Scientific Laboratory, Physics Division, 1973; and the Japanese Laboratory for High Energy Physics, Kō Enerugī Kasokuki Kenkyū Kikō, (KEK), 1982 and 1993. He has also served as senior physicist and manager for the Argonne National Laboratory, Solid State Science Division, Intense Pulsed Neutron Source Project, 1975–1978; technical director for the Intense Pulsed Neutron Source Project, 1978; senior technical advisor for the Oak Ridge National Laboratory, Spallation Neutron Source project, Experimental Facilities Division, 1998, and the Rutherford-Appleton Laboratory, periodically since 1997; and as adjunct professor of nuclear engineering and member of the graduate faculty of Iowa State University, 1987–1989.[4]
Carpenter served as a member of the 1977 U.S. Delegation to the USSR on Fundamental Properties of Matter, Item 21 of the 1973 Nixon-Brezhnev Agreement on US-USSR Cooperation in Research, Development and Utilization of Nuclear Energy; the Pennsylvania State University College of Engineering Industrial and Professional Advisory Council, 1984–1986; the National Steering Committee for the Advanced Neutron Source, 1986–1996; the Visiting Committee for the Massachusetts Institute of Technology Department of Nuclear Engineering, 1989–1995; the External Review Committee for the Los Alamos Accelerator Production of Tritium project, 1993–1998; the International Scientific Council of AUSTRON, Verein zur Förderung einer Großforschungsanlage in Österreich, from 1993; the Technical Advisory Committee of the European Spallation Source, from 2001; and the Oak Ridge National Laboratory Scientific Advisory Committee for the Spallation Neutron Source, 1996–2001.[4]
Ilya Frank Prize, 1998, awarded by the Joint Institute for Neutron Studies at Dubna, Russia[16] for his role in the development of the solid methane moderator,[9]
