John Penrose Barton (born 1934) is a British and American applied nuclear scientist who helped pioneer Neutron Radiography.
[12][13] From 1961 to 1965, while affiliated with the University of Birmingham, Barton's publications included a demonstration of Cold Neutron Radiography using a 5MW reactor at AWE Aldermaston.
[5] From 1965, while affiliated with the CEA in Grenoble, Barton's publications included potentials of small source systems and a demonstration of Underwater NR using a Conical Collimator.
[17] From 1979, based in San Diego, Barton's publications included in-house NR system designs and applications to aircraft safety, a precursor of the McClellan Radiation Center, Sacramento.
[18][19] In 1989, Barton reported on the feasibility of Maneuverable Neutron Radiography System for inspection of intact aircraft at the Sacramento Air Logistics Center.
