The Levitated Dipole Experiment (LDX) was an experiment investigating the generation of fusion power using the concept of a levitated dipole. The device was the first of its kind to test the levitated dipole concept and was funded by the US Department of Energy . [ 1 ]
The Levitated Dipole Experiment (LDX) The concept of the levitated dipole was first realized when Jay Kesner of MIT and Michael Mauel of Columbia University made a joint proposal to test the concept in 1997. [3] This led to the development of two experiments: the Levitated Dipole Experiment (LDX) at MIT and the Collisionless Terrella Experiment ...
Toroidal machines can be axially symmetric, like the tokamak and the reversed field pinch (RFP), or asymmetric, like the stellarator.The additional degree of freedom gained by giving up toroidal symmetry might ultimately be usable to produce better confinement, but the cost is complexity in the engineering, the theory, and the experimental diagnostics.
The Princeton Field Reversed Configuration (PFRC) is a series of experiments in plasma physics, an experimental program to evaluate a configuration for a fusion power reactor, at the Princeton Plasma Physics Laboratory (PPPL). The experiment probes the dynamics of long-pulse, collisionless, [1] low s-parameter [2] field-reversed configurations ...
The Z-pinch is an application of the Lorentz force, in which a current-carrying conductor in a magnetic field experiences a force.One example of the Lorentz force is that, if two parallel wires are carrying current in the same direction, the wires will be pulled toward each other.
The deuterium-tritium fusion reaction generates mono-energetic neutrons with an energy of 14.1 MeV. In fusion power plants, neutrons will be present at fluxes in the order of 10 18 m −2 s −1 and will interact with the material structures of the reactor by which their spectrum will be broadened and softened.
A wide variety of experiments on the system demonstrated that the ions were thermalizing at about 15 million Kelvin, much hotter than ZETA and hot enough to explain the neutrons if they were from fusion reactions. This was the first clear evidence that thermonuclear fusion reactions of deuterium in the lab were possible. [23] [24]
By the late 1970s, many of the design problems were considered solved, and Lawrence Livermore Laboratory began the design of the Mirror Fusion Test Facility (MFTF) based on these concepts. The machine was completed in 1986, but by this time, experiments on the smaller Tandem Mirror Experiment revealed new problems. In a round of budget cuts ...
