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 method of imploding an Inertial Confinement Fusion (ICF) target may include directing laser energy into a hohlraum, where a target is disposed within the hohlraum that includes an ablator layer, a shell disposed within the ablator layer, and a fuel region disposed within the shell. The method may also include ablating the ablator layer in response to the laser energy being directed into the hohlraum, and generating a single shockwave that is driven inward through the ablator layer. The method may further include impulsively accelerating the shell inward when hit by the single shockwave, and compressing the fuel region by the inward acceleration of the shell.

摘要： A hohlraum for an inertial confinement fusion power plant is disclosed. The hohlraum includes a generally cylindrical exterior surface, and an interior rugby ball-shaped surface. Windows over laser entrance holes at each end of the hohlraum enclose inert gas. Infrared reflectors on opposite sides of the central point reflect fusion chamber heat away from the capsule. P2 shields disposed on the infrared reflectors help assure an enhanced and more uniform x-ray bath for the fusion fuel capsule.

摘要： A fusion reactor includes an improved ability to modulate a plasma for specific purposes. The reactor operates on the ability to change at least four separate variables in each of a plurality of lenses that are independent of the other lenses. This allows for the generation of Alfvén waves and modulation of the internal plasma dynamics, actively leading to higher states of efficiency. By combining modulation of a plasma in the form of an ion beam with a solid state metal target, an efficient fast neutron source can be produced. This can lead to industrial applications such as energy generation, nuclear clean-up, the production of rare earth metals out of semi-rare ones, and helium production.

摘要： An Electron-coupled transformer for generating a high voltage output pulse as an amplified version of an input pulse comprises a cylindrical triode electron tube with a central anode along main axis and a grid and cathode radially spaced from the anode. The anode has a first end connected to ground and a second end insulated with respect to said ground. The cathode and the grid form a traveling wave electron gun that produces a wave of ground potential in the Transverse Electric Mode, which causes electrons stored in the cathode-grid gap to be extracted from said gap. The extracted electrons form a radially symmetric collapsing traveling wave that sweeps as a wave along the anode at the speed of light, causing a voltage output pulse on the second end of the anode whose magnitude is an amplified version of an input pulse applied to the cathode.

摘要： Application of axial seed magnetic fields in the range 20-100 T that compress to greater than 10,000 T (100 MG) under typical NIF implosion conditions may significantly relax the conditions required for ignition and propagating burn in NIF ignition targets that are degraded by hydrodynamic instabilities. Such magnetic fields can: (a) permit the recovery of ignition, or at least significant alpha particle heating, in submarginal NIF targets that would otherwise fail because of adverse hydrodynamic instability growth, (b) permit the attainment of ignition in conventional cryogenic layered solid-DT targets redesigned to operate under reduced drive conditions, (c) permit the attainment of volumetric ignition in simpler, room-temperature single-shell DT gas capsules, and (d) ameliorate adverse hohlraum plasma conditions during laser drive and capsule compression. In general, an applied magnetic field should always improve the ignition condition for any NIF ignition target design.

摘要： An architecture for a fusion power plant is disclosed. The plant includes a fusion chamber for producing neutrons from a fusion reaction, and a laser system in which lasers are arranged about a vacuum chamber to provide energy to the fusion chamber to initiate the fusion reaction. The beam paths between the lasers and the fusion chamber are configured to prevent neutrons from the fusion chamber from reaching the laser system at a level that would preclude human access to the laser system.
