ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Spatial and temporal spectroscopic measurements in the wavelength range from visible to soft X-ray lights are powerful tools for fusion research. We have constructed absolutely calibrated two-dimensional visible-ultraviolet (V/UV, 2500-7000 Å), Vacuum ultraviolet (VUV, 150-1050 Å) and soft X-ray (SX, 20-350Å) spectroscopic measurement systems for quantitative analysis of impurity ion behavior in the tandem mirror GAMMA 10. Carbon, oxygen and nitrogen ions are main impurity ions observed in the GAMMA 10 plasma. Using absolute emissivities of impurity lines and the collisional-radiative model, impurity ion density profiles are obtained. Moreover, we observed the plasma rotation velocity in order to measure the electric field profile by using V/UV spectrograph in the hot ion mode plasma at the first time. Then, the obtained electric field profile in the central cell is almost equal to the result of beam probe measurements.
