Monte-Carlo simulations of spinodal ordering and decomposition in compositionally modulated alloys
(Materials Research Society, 1990)
Efficiency and angular resolution calculations for a prototype multiple Compton scatter camera
(Elsevier, 1994-06-15)
Monte Carlo simulations were performed to optimize the layer thickness of a Compton camera which utilizes multiple Compton scatterings. The optimum layer thickness was found to be less than 0.5 mm for 150 keV, 2 mm for 511 ...
Digital techniques for real-time pulse shaping in radiation measurements
(Elsevier, 1994-12-30)
Recursive algorithms for real-time digital pulse shaping in pulse height measurements have been developed. The differentiated signal from the preamplifier (exponential pulse) is amplified and then digitized. Digital data ...
Temperature dependence of deformation-assisted crystallization in amorphous Fe78B13Si9Fe78B13Si9
(The American Institute of Physics, 1998-09-28)
Low-energy ball milling of amorphous Fe78B13Si9Fe78B13Si9 has been performed at temperatures between 25 and 250 °C. Primary crystallization is observed after milling at elevated temperatures, but not after annealing at the ...
Commentary: Reflections on “Quasielastic scattering by dilute polymer solutions,” by A. Z. Akcasu and H. Gurol, J. Polym. Sci., Polym. Phys. Ed. , 14, 1 (1976).

High accuracy determination of the shape of the efficiency curve of the HPGe detector in the energy range 900 to 1300 keV
(Elsevier, 1994-12-30)
A method for high accuracy characterization of the shape of a High Purity Germanium (HPGe) detector efficiency curve has been developed. Radionuclides with decay schemes having at least two [gamma] lines, for which the ...
Effects of proton irradiation on the microstructure and microchemistry of type 304L stainless steel
(Elsevier, 1993-10)
A research program has been undertaken to determine the origins of irradiation-assisted stress corrosion cracking (IASCC) in austenitic alloys in light water reactors, and the effect of impurities on IASCC susceptibility. ...
Gamma-ray spectral imaging using a single-shutter radiation camera
(Elsevier, 1990-12-20)
As part of a program to develop mobile robots for reactor environments, we are developing a radiation-imaging camera capable of operating in medium-intensity (Z scintillator. The raster-scanning camera uses a lead-shielded ...
Effects of irradiation on intergranular stress corrosion cracking
(Elsevier, 1994-10)
Intergranular stress corrosion cracking (IASCC) is a pervasive and generic problem in current light water reactor and advanced reactor designs that can lead to widespread component failure. IASCC is believed to be due to ...
