The four dopants (Nd, Gd, Dy, and Er) substitutionally occupy the Li+ sites in lithium tetraborate (Li2B4O7: RE) glasses as determined by analysis of the extended X-ray absorption fine structure. The dopants are coordinated by 6-8 oxygen at a distanc

In this work, we identify, isolate, and characterize hot particles from bulk soil samples collected from a non-critical nuclear detonation site. Several non-destructive techniques were used to identify and isolate the nuclear fuel particles from soil

Adaptive-Hybrid Redundancy (AHR) shows promise as a method to allow flexibility when selecting between processing speed and energy efficiency while maintaining a level of error mitigation in space radiation environments. Whereas previous work demonst

This paper describes the ATHENA platform, an energy tuning assembly, which was developed to spectrally shape the National Ignition Facility (NIF) deuterium–tritium fusion neutron source to a thermonuclear (fusion) plus prompt fission neutron spectr

Radiation hardened by design processors are used in space environments to ensure reliability. These processors are difficult to develop, prohibitively expensive, and not state-of-the-art. Researchers now examine commercial processors and field progra

Single crystals of ThO2, UO2, and their solid solutions, UxTh1–xO2, have been obtained through various hydrothermal growth conditions. This technique offers the better of two other growth processes: (i) single crystal purity as by photochemical gro

The integration of photoconductive semiconductor switches (PCSSs) into pulsed power systems may have improvements over conventional switching, but failure modes occurring near the illuminated edge of PCSS devices between switching operations present
