3. Undergraduate Research at the University of Dallas: B.S. requires a research project, an undergraduate thesis, and a talk at a professional meeting (56/60 B.S. in last 10 years) Outside research a necessity for students to fulfill the research requirement, e.g., NEUP research at the University of Kentucky. Luke Kersting 2010 Leslie Sidwell and Brett Combs 2012

4. Elastic /Inelastic Measurement Project  Critical need for high-precision and accurate elastic and inelastic neutron scattering data on materials important for fission reactor technology. Once obtained the data are sent to data evaluators.  Critical need for trained individuals. (NEUP initiative puts undergraduate students on the right pathway to becoming scientists and engineers.)  Part of the Advanced Fuel Cycle Initiative (AFCI) to develop safe, clean, and affordable energy sources. http://www.gen-4.org/Technology/evolution.htm Goals of Gen IV: i)Safer ii)Sustainable iii)Economical iv)Physically Secure ARUNA 2014

5. “A Technology Roadmap for Generation IV Nuclear Energy Systems,” Generation IV International Forum, December 2002. One of the Six Generation IV Nuclear Energy Systems Inelastic Neutron Scattering Energy Loss Mechanism Fe * Neutron elastic and inelastic scattering cross sections are needed off of structural material such as Fe and coolants such as Na. ARUNA 2014

6. Inelastic Neutron Scattering Energy Loss Mechanism Fe * Relative Detector Efficiency 54 Fe at E n =3.0 MeV Student Projects: Participate in measurements at UKAL Analyze data sets, e.g., two or more angular distributions of elastically and inelastically scattered neutrons and a detector efficiency Solid line is ENDF model calculations

7. ARUNA 2014 Relative Detector Efficiency 54 Fe at E n =3.0 MeV Student Projects: Participate in measurements at UKAL Determine a detector efficiency Analyze two or more angular distributions of elastically and inelastically scattered neutrons Solid line is ENDF model calculations

8. ARUNA 2014 University of Dallas students have participated in nuclear structure and neutron scattering measurements at UKAL since 1990. Advantages: Students participate in all aspects of the measurements. A much better teaching environment than going to a more traditional user facility, e.g., the PSI. Projects are manageable in 10 weeks in the summer.
