The Levitated Dipole eXperiment

Welcome to the Levitated Dipole eXperiment (LDX) web site. LDX is a novel experimental device designed to explore the physics of plasma confinement in a magnetic dipole field. What makes it unique? Besides levitating a 1/2 ton superconducting ring, we will conduct the first experimental test on the theory of plasma confinement by adiabatic compressibility. If this concept turns out to be correct, levitated dipoles may one day make an attractive magnetically confined fusion energy source. LDX is a collaboration between Columbia University's Dept. of Applied Physics and the MIT Plasma Science & Fusion Center and is funded by the Department of Energy's Office of Fusion Energy.

Fusion research has focused on the goal of a fusion power source that utilizes deuterium and tritium (D-T) because the reaction rate is relatively large compared with the rate for D-D or D-He3. Furthermore, the D-D cycle is difficult in a traditional fusion confinement device such as a tokamak because good energy confinement is accompanied by good particle confinement which leads to a build up of ash in the discharge.

Previous studies [1-4] indicate that a levitated dipole would be favorable for a D-He3 fuel cycle based power source. The D-D cycle is the most promising because of the availability of deuterium. Recently we have considered utilizing a levitated dipole for the D-D cycle based power source. Fusion reactors based on the deuterium-deuterium (D-D) reaction would be superior to D-T based reactors in so far as they can greatly reduce the power produced in neutrons and do not requires the breeding of tritium. In a recent article titled "Helium Catalyzed D-D Fusion in a Levitated Dipole" we have proposed a fusion power source, based on an alternative fuel cycle which we call ``helium catalyzed D-D". We have explored the application of a levitated dipole as a D-D power source and found that a dipole may have the unique capability of producing excellent energy confinement accompanied by low particle confinement. Additionally a levitated dipole device would be intrinsically steady state and extract power as surface heating, permitting a thin walled vacuum vessel and eliminating the need for a massive neutron shield. We find that a dipole based D-D power source can potentially provide a substantially better utilization of magnetic field energy with a comparable mass power density as compared to a D-T based tokamak power source.

Kinda takes the weight off a spacecraft engine if it's 'levitating" :P

Only problem is... all the HE3 is on the MOON

You would need one of these 'Aquila Class Liquid Cargo Transports" to bring it home..

Method of Delivering Lunar Generated Fluid
to Earth Orbit Using an External Tank
Publication number: US5092545
Publication date: 1992-03-03
Applicant: NASA (US)


A method and apparatus are provided for delivering lunar generated fluid to Earth orbit from lunar orbit. Transport takes place in an external tank of a shuttle which has been suitably outfitted in Earth orbit for reusable travel between Earth orbit and a lunar orbit. The outfitting of the external tank includes the adding of an engine, an electrical system, a communication system, a guidance system, an aerobraking device, and a plurality of interconnected fluid storage tanks to the hydrogen and oxygen tanks of the external tank. The external tank is then propelled to lunar orbit the first time using Earth based propellant. In lunar orbit, the storage tanks are filled with the lunar generated fluid with the remainder tank volumes filled with lunar generated liquid oxygen and hydrogen which serve as propellants for returning the tank to Earth orbit where the fluid is off-loaded. The remaining lunar generated oxygen and hydrogen is then sufficient to return the external tank to lunar orbit so that a subsequent cycle of fluid delivery is repeated. A space station in a higher Earth orbit is preferably used to outfit the external tank, and a lunar node in lunar orbit is used to store and transfer the fluid and liquid oxygen and hydrogen to the external tank. The lunar generated fluid is preferably 3He.
