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 measurement of the plasma current profile is crucial to many operating regimes and investigations on the DIII-D tokamak. The measurement is required to obtain accurate equilibria and to accurately calculate stability and transport characteristics of the plasma. The measurement of the profile is also required to obtain the different components of the current to guide efforts on the control of the current profile and experiments toward obtaining steady-state operating regimes. The edge current profile measurement is necessary to understand the formation of edge pedestal and edge-localized modes. The DIII-D tokamak has a three-array, 45-channel motional Stark effect (MSE) diagnostic to measure the plasma current density and radial electric field. A 32-channel lithium-beam (Li-beam) diagnostic has recently been installed on the DIII-D tokamak for the measurement of edge current density. Both diagnostics measure the current profile from the measurement of the pitch angle of the magnetic field that, in turn, is derived from the orientation angle of polarization of the appropriate neutral beam spectral line. The MSE and the Li-beam diagnostics are described, and some examples of measurements are shown.
