Investigation of the Shape of Beta Spectra at the Low-Energy End

Description: The applicability of proportional counting to low-energy p-spectra has been demonstrated. As yet, however, nothing has been primarily directed toward the general problem of spectral shapes at the low-energy end. This report attempts to address that and to resolve questions about it experimentally.

Mass Transfer by High Temperature Liquid Sodium. Interim Progress Report 1

Description: The general objective of the program is to increase existing knowledge on the behavior of solid metals in liquid metal environments. Higher temperatures, longer operating life, and increase reliability of liquid metal cooled reactors is the ultimate goal. The initial phase of the program is concerned primarily with an experimental investigation of corrosion and mass transfer by sodium in dynamic, monometallic polythermal systems, at temperatures in the range from 1000 - 1600 F. Research in diff… more

A Study of the Nuclear Reactions Mg26 ( p , t ) Mg24 and Mg26 ( He4 , He6 ) Mg24

Description: A comparison of spectra and distributions is made for the two neutron pickup reactions [formula]. The energies are such that the ground state pickup momentum transfers at 15° lab are equal permitting a study of the relative excitations for transitions to the discrete state observed. Comparisons are made for the ground [formulas] states. Unresolved structure at higher energies is compared in terms of its gross properties. During the course of the measurements, higher charge particles were also o… more

Leaching of Cadmium, Tellurium and Copper From Cadmium Telluride Photovoltaic Modules.

Description: Separating the metals from the glass is the first step in recycling end-of-life cadmium telluride photovoltaic modules and manufacturing scrap. We accomplished this by leaching the metals in solutions of various concentrations of acids and hydrogen peroxide. A relatively dilute solution of sulfuric acid and hydrogen peroxide was found to be most effective for leaching cadmium and tellurium from broken pieces of CdTe PV modules. A solution comprising 5 mL of hydrogen peroxide per kg of PV scrap … more

Single Molecule Techniques for Advanced in situ Hybridization

Description: One of the most significant achievements of modern science is completion of the human genome sequence, completed in the year 2000. Despite this monumental accomplishment, researchers have only begun to understand the relationships between this three-billion-nucleotide genetic code and the regulation and control of gene and protein expression within each of the millions of different types of highly specialized cells. Several methodologies have been developed for the analysis of gene and protein … more

Results from the First {sup 249}Cf + {sup 48}Ca Experiment

Description: The present paper reports the results of an attempt aimed at the synthesis of element 118 in the reaction {sup 249}Cf({sup 48}Ca,3n){sup 294}118. The experiment was performed employing the Dubna Gas-filled Recoil Separator and the U400 heavy-ion cyclotron at FLNR, JINR, Dubna. In the course of a 2300-hour irradiation of an enriched {sup 249}Cf target (0.23 mg/cm{sup 2}) with a beam of 245-MeV {sup 48}Ca ions, we accumulated a total beam dose of 2.5 x 10{sup 19} ions. We detected two events that… more

Long Range, Passive Detection of Fissile Materials

Description: We have recently completed a large-area, coded-aperture, gamma-ray imager for use in searching for radiation sources. The instrument was constructed to verify that weak point sources can be detected at considerable distances if one uses imaging to overcome fluctuations in the natural background. The instrument uses a rank-19, one-dimensional coded aperture to cast shadow patterns onto a 0.57 m{sup 2} NaI(Tl) detector composed of 57 individual cubes each 10 cm on a side. These are arranged in a … more

A Bright Source of High-Energy X-rays: Final Report on LDRD Project 04-FS-007

Description: We have demonstrated the feasibility of fabricating pure-metal foams via a novel four-step technique based upon ion beam lithography. In this report we discuss why and how such foams are useful as bright, high-photon-energy x-ray sources; the details of the fabrication technique we employed to make such foams; the results obtained; and what we plan to do in the future to improve the technique and turn the foams so fabricated into real laser targets for high-brightness, high-energy back lighting. more

Development of a Rolling Process Design Tool for Use in Improving Hot Roll Slab Recovery Quarterly Report: Q1 FY03

Description: In this quarter, further analysis was done to investigate the difficulty in predicting fracture at the slab ends. The stress concentration created by the notch geometry at the slab ends can accelerate damage and promote fracture at the relatively low strain rates that exist when the notch region is not directly in the roll bite. However, the phenomenological fracture model provided by Alcoa Technical Center (ATC) was calibrated for strain rates characteristic of the rolling process zone and hyd… more
