Abstract70728 The neutron energy levels desired for the next generation of neutron choppers, used in materials science research, require rotational speeds that exceed the capabilities of traditional materials. Advanced composite materials offer the capability of obtaining the speeds desired, along with the necessary large aperture sizes. To address the technology issues associated with the use of these advanced materials, this project will combine focused risk-reduction research with detailed computer simulations of chopper designs that use the new materials. The risk-reduction will address the unique environment of a chopper design, and the effects on composite materials. The computer simulation will be used to optimize novel configurations that take the greatest advantage of these materials. Phase I will address the effects of neutron radiation on organic matrix composite materials (such as graphite reinforced epoxy). Two chopper designs will result: one design will use an organic matrix composite, while the other will use a non-organic matrix, such as a ceramic. Commercial Applications and Other Benefits as described by the awardee: Numerous neutron spectrometers throughout the world are looking to upgrade their instrumentation. Besides the Fermi chopper, the technology will apply to any of the other choppers, or any instruments that involve high-speed rotating components.
