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.

Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

In the GAMMA10 tandem mirror, waves with ion cyclotron range of frequency (ICRF) have been used for plasma production and heating. Magneto Hydro Dynamic (MHD) stability is kept with the anchor cells which have minimum-B configuration. In a typical discharge, plasmas in the anchor cell are heated with ICRF waves excited by Type-III antennas installed in the central cell. In order to produce high performance plasma, anchor heating should be enhanced. Double-Arc Type (DAT) antennas are installed in both east and west anchor cells. In this study, direct heating experiments in both east and west anchor cells with DAT antenna are performed. DAT antenna is driven with the different frequency from Type-III antenna and driven with the same frequency. In the same frequency case, the phase difference between both antennas can be changed. In both the different and the same frequency cases, the increase of the line density is clearly observed in the central and anchor cells. Stronger effects are observed in the east anchor than in the west anchor.
