Experimental attempt to achieve microstructure variations through temperature/time permutations for a nonwrought powder metallurgy uranium-6 niobium alloy

Description: The powder metallurgical processing of uranium-6 niobium (U-6Nb) alloy has undergone 3 years of characterization at the Oak Ridge Y-12 Plant. The current structure of the powder metallurgy (P/M) alloy has been described as duplex: a mixture of two or more distinct grain sizes. An experiment was conducted to determine a gamma stabilizing heat treatment (time and temperature combination) to produce a structure consisting of one gamma grain size. Two heat treatments were found to produce an irregu… more

High Brightness Test Stand

Description: The High Brightness Test Stand is a 2 MeV, less than or equal to 10 kA electron accelerator module. This accelerator module, designed as an upgrade prototype for the Advanced Test Accelerator (ATA), combines solid state nonlinear magnetic drives with state-of-the-art induction linac technology. The facility serves a dual role, as it not only provides a test bed for this new technology, but is used to develop high brightness electron optics. We will both further describe the accelerator, as well… more

Titanium-getter testing for TMX-U

Description: This report summarizes the results of titanium-gettering tests performed during August and September of 1983. Several current and voltage schedules were evaluated for possible implementation with TMX-U's computer-controlled getter system. The tests were performed using 1/8-inch wire composed of 85% Ti and 15% Ta. Measurements of wire temperature as a function of getter current were made. We performed glow discharge cleaning (GDC) of the vessel with wires in place to determine if GDC had any adv… more

New harmonic materials: index engineering. Thin-thick quadrature frequency conversion

Description: The quadrature conversion scheme is a method of generating the second harmonic. The scheme, which uses two crystals in series, has several advantages over single-crystal or other two crystal schemes. The most important is that it is capable of high conversion efficiency over a large dynamic range of drive intensity and detuning angle. Consider a pair of KDP crystals cut for type-II phase matching. In the quadrature scheme, the optic axes of the crystals are arranged so that the plans containing… more

Resolvability of positron decay channels

Description: Many data analysis treatments of positron experiments attempt to resolve two or more positron decay or exist channels which may be open simultaneously. Examples of the need to employ such treatments of the experimental results can be found in the resolution of the constituents of a defect ensemble, or in the analysis of the complex spectra which arise from the interaction of slow positrons at or near the surfaces of solids. Experimental one- and two-dimensional angular correlation of annihilati… more

Difficulties with inferring neutron cross sections from charged-particle reactions

Description: We have investigated problems associated with inferring cross sections for neutron reactions on unstable nuclei in the mass-90 region from charged-particle reactions on nearby stable targets. We conclude that effects due to precompound evaporation, isospin, and multiple reaction paths severely limit the circumstances under which charged-particle studies may be directly and easily converted to neutron cross sections of useful accuracy. 4 refs., 2 figs.

Importance of level structure in nuclear reaction cross-section calculations. Revision 1

Description: It is shown that level-density expressions cannot adequately represent or substitute for level structure information when making calculations of the Hauser-Feshbach type for cross sections or isomer-ratios for nuclei in the first few MeV above their ground state. It is stated that such discrete level information should include both experimentally confirmed and theoretically predicted levels. The utility of discrete level information to optimize level density calculations, to compute isomer rati… more

Calculational tools for the evaluation of nuclear cross-section and spectra data

Description: A technique based on discrete energy levels rather than energy level densities is presented for nuclear reaction calculations. The validity of the technique is demonstrated via theoretical and experimental agreement for cross sections, isomer-ratios and gamma-ray strength functions. 50 refs., 7 figs. (WRF)
