DEFENSE -- Real war games . . .

Dan Tufano spends a lot of time in his Ballistic Missile Defense System mode, thinking about human behavior, decision-making and how people interact with screens and machines. If the United States ever comes under attack, his work with the Missile Defense Agency and Joint Air and Missile Defense organization could play a role in determining the outcome. "As the Ballistic Missile Defense System continues to grow, it will become increasingly complex and include multiple types of weapons and sensors distributed across the globe," said Tufano, an experimental psychologist at Oak Ridge National Laboratory. To ensure that the U.S. is prepared, each year he participates in a number of war games designed to help participants work collaboratively and with a multitude of automated systems in real and accelerated time scenarios. The war games are coordinated through either the Missile Defense Agency or the Joint Air and Missile Defense Organization. [Contact: Ron Walli, (865) 576-0226; wallira@ornl.gov]

INSTRUMENTATION -- Stressed out . . .

Quick, accurate location and measurement of potential failure points in materials is the focus of a second-generation neutron residual stress mapping instrument jointly developed by Oak Ridge National Laboratory and the University of Tennessee. The project, headed by Cam Hubbard of ORNL's Metals and Ceramics Division, uses high-flux neutron beams from the lab's High Flux Isotope Reactor to measure residual stress and create a three-dimensional map pinpointing high stress locations of likely materials failure. The instrument also can study the grains in a material and how they react when going through a deformation process, helping to improve the manufacturing process of engines
