Detection of special nuclear material from delayed neutron emission induced by a dual-particle monoenergetic source
Detection of unique signatures of special nuclear materials is critical for their interdiction in a variety of nuclear security and nonproliferation scenarios. We report on the observation of delayedExpand

Numerical studies of multimodal phase-sensitive parametric amplification
In the presence of a nonzero idler beam or, equivalently, in the collinear degenerate configuration, optical parametric amplification (OPA) can be phase sensitive. When the photon deamplificationExpand

Development and characterization of a neutron detector based on a lithium glass–polymer composite
Abstract We report on the fabrication and characterization of a neutron scintillation detector based on a Li-glass–polymer composite that utilizes a combination of pulse height and pulse shapeExpand

Plume dynamics and gas-phase molecular formation in transient laser-produced uranium plasmas
The dynamics of expansion, thermodynamics, and chemical reactions in laser-produced plasmas is of general interest for all laser ablation applications. This study investigates the complex morphologyExpand

Time-resolved imaging of atoms and molecules in laser-produced uranium plasmas
Gas-phase oxidation of uranium (U), plume chemistry, and the corresponding impact on optical emission features of the U plasma are investigated. Plasmas were produced via nanosecond laser ablation ofExpand
