Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight

A filter charge exchange recombination spectroscopy (CXRS) system has been developed for the real-time measurement and feedback control of ion temperature (Ti) profiles in JT-60U. In order to improve the dynamic range and the spatial coverage, the passband of each filter used for the fast CXRS diagnostic is optimized for the target value of Ti (~0.1-20 keV), and the number of relevant channels is increased (maximum: 12 channels). Real-time processor system has also been improved using advantage of the filter CXRS method. Utilizing this filter CXRS system, real-time control of the central Ti has been demonstrated.
