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.

Elastic and one-phonon inelastic scattering cross sections of neutrons in graphite have been calculated for neutron energy less than 2000 k0. For the lattice vibrations in graphite, the model proposed by Krumhansl and Brooks has been used. We have also calculated the mean energy loss per collision and the mean logarithmic energy decrement. Assuming that close to equilibrium the neutron distribution remains Maxwellian, the time variation of the temperature of this distribution has been calculated. The slowing down relaxation time near equilibrium comes out to nearly 170 µsec, which compares well with the experimental value of 185 ± 45 µsec.
