ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.

The energy and angular distributions of the protons from the 93Nb(n, xp) reactions were investigated by means of the Vienna multitelescope system. Whereas total hydrogen production cross sections are in fair agreement with previous results, considerable deviations from a previous measurement of the shape of the angle-integrated proton spectrum have been found. No other detailed measurements of the angular distributions have as yet been reported. The angle-integrated results are compared with calculations based on the statistical model of nuclear reactions, including precompound processes. It is shown that the proton emission spectrum can be described within this model if the usual pairing correction is also used for the exciton state densities within precompound calculations and otherwise a set of parameters which gives an adequate description of all other neutron-induced reactions of 93Nb. The angular distributions, which show a strongly energy-dependent forward-backward asymmetry, are compared to the results of a phenomenological model and to those of direct reaction theory for continuum cross sections.
