One of the beams may be replaced by a static target, in which case the approach is termed accelerator based fusion or beam-target fusion, but the physics is the same as colliding beams. [ 1 ] CBFRs face several problems that have limited their ability to be seriously considered as candidates for fusion power .

Neutral-beam injection (NBI) is one method used to heat plasma inside a fusion device consisting in a beam of high-energy neutral particles that can enter the magnetic confinement field. When these neutral particles are ionized by collision with the plasma particles, they are kept in the plasma by the confining magnetic field and can transfer ...
Colliding beam fusion: A beam of high energy particles fired at another beam or target can initiate fusion. This was used in the 1970s and 1980s to study the cross sections of fusion reactions. [8] However beam systems cannot be used for power because keeping a beam coherent takes more energy than comes from fusion.
Producing an energy yield of 0.72, of laser beam input to fusion output. [78] [79] [Record] On December 5, the National Ignition Facility recorded the first experiment to surpass scientific breakeven, achieving an energy gain factor of Q = 1.54, producing more fusion energy than the laser beam delivered to the target. Laser efficiency was in ...
A high-energy beam of deuterium ions generated by pyroelectric crystals was directed at a stationary, room-temperature ErD 2 or ErT 2 target, and fusion was observed. [ 2 ] In previous fusion research, such as inertial confinement fusion (ICF), fuel such as the rarer tritium is subjected to high pressure for a nano-second interval, triggering ...
Magnetized target fusion (MTF) is a fusion power concept that combines features of magnetic confinement fusion (MCF) and inertial confinement fusion (ICF). Like the magnetic approach, the fusion fuel is confined at lower density by magnetic fields while it is heated into a plasma. As with the inertial approach, fusion is initiated by rapidly ...
The target is a small spherical pellet containing a few milligrams of fusion fuel, typically a mix of deuterium (D) and tritium (T), as this composition has the lowest ignition temperature. [ 16 ] The lasers can either heat the surface of the fuel pellet directly – known as direct drive – or heat the inner surface of a hollow metal cylinder ...
