摘要： Embodiments of a laser system having an extremely large number of small pulsed lasers for irradiating small targets in inertial confinement fusion experiments, high energy density physics experiments, and inertial fusion power plants is more flexible than existing laser systems. Embodiments facilitate finer control of critical features of laser pulses for inertial fusion, as well as significant reduction in development costs and expansion of the community involved in the research relative to existing laser systems. Embodiments produce smooth intensity profiles at the target, large bandwidth that is over two orders of magnitude greater than existing laser systems, and fine control over laser wavelengths, focal properties, temporal pulse shape, and illumination geometry. Properties of each of the small pulsed lasers are individually selectable.

摘要： A system and method is disclosed for detecting fissionable materials. In one embodiment the system may incorporate a neutron pulse generator configured to generate multiple short pulses of neutrons, or a single pulse of sufficient intensity, in a vicinity of an object of interest. The source pulse of neutrons includes neutrons which each have a full width half maximum time duration of less than about 100 ns and a peak energy level no greater than about 20 MeV. A fast response detector is used which is able to detect single neutron events indicative of fission neutrons having been produced by the source pulse of neutrons interacting with fissionable material associated with the object of interest, and which arrive at the fast response detector within a predetermined time window immediately before arrival of the source neutron pulses.

摘要： The present architecture utilizes a Nonlinear Scattering Aperture Combiner that does not need to be optically multiplexed and then drives a Direct Compressor stage that produces a large temporal compression ratio to pump a Fast Compressor. This eliminates the need for a separate array of ATDMs, multiplexing optical elements, and, at the approximate 107 joule energy output required for ICF, reduces the number of mechanical elements and gas interfaces from the order of 103 to about 10. In addition, this provides a large reduction of the volume of the gas containment region. In order to accomplish this, a technique for transversely segmenting by color and/or polarization of the optical extraction beams of the Direct Compressor has been invented. In particular, it is directed towards the integration of the Direct Compressor with the Primary Laser Source and Fast Compressor. The embodiments describe how the high operating fluence are addressed in terms of avoiding optical damage and how to integrate the stages in fluid mechanical and optical aspects.

摘要： A method of igniting a deuterium-tritium ICF fuel target to obtain fuel burn in which the fuel target initially includes a hollow spherical shell having a frozen layer of DT material at substantially uniform thickness and cryogenic temperature around the interior surface of the shell. The target is permitted to free-fall through a target chamber having walls heated by successive target ignitions, so that the target is uniformly heated during free-fall to at least partially melt the frozen fuel layer and form a liquid single-phase layer or a mixed liquid/solid bi-phase layer of substantially uniform thickness around the interior shell surface. The falling target is then illuminated from exteriorly of the chamber while the fuel layer is at substantially uniformly single or bi-phase so as to ignite the fuel layer and release energy therefrom.
