A schematic of a fusion-driven rocket by NASA. A fusion rocket is a theoretical design for a rocket driven by fusion propulsion that could provide efficient and sustained acceleration in space without the need to carry a large fuel supply. The design requires fusion power technology beyond current capabilities, and much larger and more complex ...
The high temperature of a fusion plasma precludes the use of material vessels for direct containment. Magnetic confinement fusion attempts to use the physics of charged particle motion to contain the plasma particles by applying strong magnetic fields. Tokamaks and stellarators are the two leading MCF device candidates as of today ...
Conventional metals such as steel would have a short lifetime and require frequent replacement of the core containment walls. Another concern is fusion afterdamp (debris left in the reaction chamber), which could interfere with subsequent shots, including helium ash produced by fusion, along with unburned hydrogen and other elements used in the ...
[13] The term "tokamak" was coined in 1957 [14] by Igor Golovin, a student of academician Igor Kurchatov.It originally sounded like "tokamag" ("токамаг") — an acronym of the words "toroidal chamber magnetic" ("тороидальная камера магнитная"), but Natan Yavlinsky, the author of the first toroidal system, proposed replacing "-mag" with "-mak" for euphony.

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 fusion took place in a 2.5 metres (8 ft 2 in) target chamber that was surrounded by 40 short tons (36,000 kg) of unenriched fission fuel, or alternately about 7 short tons (6,400 kg) of Pu or highly enriched uranium from weapons. The fusion system was expected to produce Q on the order of 25 to 30, resulting in 350 to 500 MW of fusion energy.

In fusion power research, the Z-pinch (zeta pinch) is a type of plasma confinement system that uses an electric current in the plasma to generate a magnetic field that compresses it (see pinch). These systems were originally referred to simply as pinch or Bennett pinch (after Willard Harrison Bennett ), but the introduction of the θ-pinch ...
