Fuel capsules usable in inertial confinement fusion (ICF) reactors have shells made from materials having a diamond (sp.sup.3) lattice structure, including diamond materials in synthetic crystalline, polycrystalline (ordered or disordered), nanocrystalline and amorphous forms. The interior of the shell is filled with a fusion fuel mixture, including any combination of deuterium and/or tritium and/or helium-3 and/or other fusible isotopes.

Method and apparatus for heating and/or compressing plasmas to thermonuclear temperatures and densities are provided. In one aspect, at least one of at least two plasmoids separated by a distance is accelerated towards the other. The plasmoids interact, for instance to form a resultant plasmoid, to convert a kinetic energy into a thermal energy. The resultant plasmoid is confined in a high energy density state using a magnetic field. One or more plasmoids may be compressed. Energy may be recovered, for example via a blanket and/or directly via one or more coils that create a magnetic field and/or circuits that control the coils.

A particle beam emitter has a hollow particle beam tube having a first end portion, a second end portion, and a longitudinal axis. An electromagnetic system that includes a voltage supply is electrically coupled to the hollow particle beam tube and is configured to generate a primary electrical current flowing axially in the hollow particle beam tube from the first end portion towards the second end portion. A primary magnetic field associated with the primary electrical current is operable to induce a secondary electrical current in a plasma located within the hollow particle beam tube, the secondary electrical current flowing generally axially within the plasma and causing the plasma to contract inwardly towards the longitudinal axis.

Methods, devices and system for asymmetric inertial confinement fusion are disclosed. One method includes a fixing in position a target capsule comprising an inertial confinement fusion fuel, where the target capsule is substantially spherical. The method further includes for applying an oscillatory compression to the target capsule. The oscillatory compression includes compression at a first time in a radial direction orthogonal to a diametric axis of the target capsule, and compression at a second time along the diametric axis to drive the target capsule into driven into an ovoid shape. The oval shaped target can implode upon being further driven at a third time.

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.
