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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

A method is described for suppressing secondary electron emission from the negatively biased electrode of a beam direct energy converter by surrounding it with magnetic field lines. Experiments in a positive ion beam converter with a magnetically protected suppressor have shown that the secondary electrons generated by ion bombardment are successfully prevented from leaving the suppressor. It is also found that backscattered ions from the positive electrode occupy a noticeable portion of the loss currents generated in a converter with a copper electrode.
