Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

The electrostatic fluctuation was observed by a heavy ion beam probe (HIBP) at the central cell in the GAMMA 10 tandem mirror. The fluctuation of the end plates settled at both side of GAMMA 10 was observed. In the plasma, as increasing of the electrostatic fluctuation, decrease of the diamagnetism and electron density was observed. The radial profile of particle transport induced by fluctuations increased substantially. A strong correlation between the potential fluctuations measured by HIBP and end plates was observed. The electrostatic fluctuation propagated from the central cell to end cell.
