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.
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
HE3 that wonder fuel that is scattered around on the moon, some trillion metric tons of it, enough to power our planet for 10,000 years (25 tonnes will power the USA for one year - 25 tonnes is the capacity of one shuttle trip - 100 tons will power the entire world for a year)

A tokamak is a machine producing a toroidal magnetic field for confining a plasma. It is one of several types of magnetic confinement devices, and it is one of the most-researched candidates for producing controlled thermonuclear fusion power.
The term tokamak is a transliteration of the Russian word токамак which itself is an acronym made from the Russian words: "тороидальная камера в магнитных катушках" (toroidal'naya kamera v magnitnykh katushkakh) — toroidal chamber with magnetic coils (possibly tochamac). An alternative, possibly older, abbreviation exists, meaning toroidal chamber with axial magnetic field (toroidal'naya kamera s aksial'nym magnitnym polem).[1] It was invented in the 1950s by Soviet physicists Igor Yevgenyevich Tamm and Andrei Sakharov (who had been inspired by an original idea from Oleg Lavrentyev[2]).

Nice potential for a containment system.
Have they managed to create a sustained fusion reaction within it?

Zorgon, you really need to leave the house a little more often... hehehe...
It's not advisable to combine work and fun at the same time.
Nice thread, by the way!

The high power helicon is a state of the art electrodeless plasma thruster. This mean that issues associated with erosion of electrode by the plasma is eliminated. The plasma itself is generated by high power radio frequency waves that allow substantial felixbility in operational characteristics. it is also very much small than other plasma thruster, which adds to to versatility.
Mini-Magnetospheric Plasma Propulsion (M2P2) is an advanced plasma propulsion system that will enable spacecraft to attain unprecedented speeds, with minimal energy and mass requirements. It will create a large scale magnetic bubble around the spacecraft to ride the solar winds, and accelerate the spacecraft to unprecedented speeds.

Are we all so jaded no one sees the significance of that? And this is just a prototype.

Yes I have been looking for a good source of that info myself. Saw it years ago, before I started saving everything. Has something to do with the Nazi saucer stuff.
If anyone has any material on that supercooled mercury plasma, I would appreciate it
