You are invited to apply to this NSF International Research Experiences for Students (IRES) summer internship at Nagoya University, Japan.  Six undergraduate and one graduate student will do research and development on the Neutron Optics Parity and Time Reversal EXperiment (NOPTREX), which will investigate the matter/antimatter asymmetry of the Universe. Recruitment, selection and training are carried out by the collaborating institutions: University of Kentucky, Indiana University, Ohio University, Berea College, Eastern Kentucky University, Western Kentucky University, Centre College, and Hendrix College. Participants will receive extensive individualized training during the academic year as they develop specialized hardware for the experiment to prepare them for specific tasks during their research in Japan the following summer. Participants will learn collaborative skills as they share their progress with each other and their Japanese mentors in weekly collaboration video conference meetings during the academic year. They will receive additional scientific and cultural awareness training during two in-person collaboration meetings before travel to Japan.
