Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy.
This kind of fusion reactor would consist of two parts: Targets which can be small capsules (<7 millimeter diameter) that contain fusion fuel. Although many kinds of targets have been tested including: cylinders, shells coated with nanotubes, solid blocks, hohlraum, glass shells filled with fusion fuel, cryogenically frozen targets, plastic shells, foam shells and materials suspended on spider ...
In June 2018 a record ion temperature of about 40 million degrees, a density of 0.8 × 10 20 particles/m 3, and a confinement time of 0.2 second yielded a record fusion product of 6 × 10 26 degree-seconds per cubic metre. [37] During the last experiments of 2018, the density reached 2 × 10 20 particles/m 3 at a temperature of 20 million ...
10-beam NIR and frequency-tripled 351 nm UV laser; fusion yield of 10 13 neutrons; attempted ignition, but failed due to fluid instability of targets; led to construction of NIF: 1.3 PW: 120 kJ: 30 J: Livermore: LLNL: ISKRA-5: Operational-1989: 12-beam iodine gas laser, fusion yield 10 10 to 10 11 neutrons [96] 100 TW: 30 kJ: 0.3 J: Sarov: RFNC ...
Proponents note that large-scale fusion power would be able to produce reliable electricity on demand, and with virtually zero pollution (no gaseous CO 2, SO 2, or NO x by-products are produced). [253] According to researchers at a demonstration reactor in Japan, a fusion generator should be feasible in the 2030s and no later than the 2050s.
The Lockheed Martin Compact Fusion Reactor (CFR) was a fusion power project at Lockheed Martin’s Skunk Works. [1] Its high-beta configuration, which implies that the ratio of plasma pressure to magnetic pressure is greater than or equal to 1 (compared to tokamak designs' 0.05), allows a compact design and expedited development. The project ...
The conversion is based on a Traveling-Wave Direct Energy Converter (TWDEC). A gyrotron converter first guides fusion product ions as a beam into a 10-meter long microwave cavity filled with a 10-tesla magnetic field, where 155 MHz microwaves are generated and converted to a high voltage DC output through rectennas.
This paper is not applicable to IEC fusion, as a quasineutral plasma cannot be contained by an electric field, which is a fundamental part of IEC fusion. However, in an earlier paper, "A general critique of inertial-electrostatic confinement fusion systems" , Rider addresses the common IEC devices directly, including the fusor.
