Technical Design
CNT, which is housed in a cylindrical vacuum chamber made of 316 stainless steel, measures 60 inches in diameter and stands 75 inches tall. The empty chamber is capable of reaching a pressure of 2x10-10 Torr.
CNT is unique in its simple geometry. Magnetic surfaces are created using only 4 electromagnetic coils - two interlocking coils inside the chamber, and two poloidal field coils outside the chamber. The two interlocking coils have a radius of .405m, and the angle between them can be manually selected to be 64°, 78°, or 88°, allowing for different shear and rotational transform values, and magnetic surface configuration. The poloidal field coils have a radius of 1.08m. The coils are powered by a 200 kW power supply and are capable of producing magnetic fields of 0.01-0.2T. The configuration of CNT creates a very low aspect ratio of 1.9, the lowest of any stellarator built.

Famous quotes containing the words technical and/or design:
“Woman is the future of man. That means that the world which was once formed in man’s image will now be transformed to the image of woman. The more technical and mechanical, cold and metallic it becomes, the more it will need the kind of warmth that only the woman can give it. If we want to save the world, we must adapt to the woman, let ourselves be led by the woman, let ourselves be penetrated by the Ewigweiblich, the eternally feminine!”
—Milan Kundera (b. 1929)
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
