@ Neutron and gamma radiation levels around a Cockcroft-Walton neutron generator producing 14-Mev neutrons at an approximate rate of 1010 neutrons per second were measured under conditions typical of those required for activation analysis. Neutron flux reduction to acceptable levels for limited operation was accomplished by 12 feet of distance that included shielding consisting of 27 inches of ...

The development of novel neutron optics devices that rely on perfect crystals and nano-scale features are ushering a new generation science experiments, from fundamental physics to material characterization emerging quantum materials. However, the standard theory dynamical diffraction (DD) analyzes propagation through does not consider complex geometries, deformations, and/or imperfections whic...

The compact neutron generator MP320 (Thermo Scientific Inc.) operating on the principle of a deuterium-tritium reaction was tested before its planned application as the neutron source for the purpose of Fast Neutron Activation Analysis applications. Plates made from Al, Fe, Sn and Si were irradiated by a 14 MeV neutron beam and typical neutron induced reactions were identified. Abstrakt Kompakt...

This paper presents the design and an analysis of a surface PM vernier generator (SPMVG) for MW-scale direct-drive (DD) wind turbine application. An SPMVG has advantage higher torque density; however, especially at power ratings with increased electrical loadings, factor worsens there are some serious concerns including magnetic saturation cores demagnetization. These issues directly related to...
