Cryostat
A true sense of size

Just like a thermos provides the insulation to keep your coffee warm—or your water cold—the 澳门六合彩高手 cryostat raises a barrier around the superconducting magnets that limits the possibility of heat exchange with the outside environment.
Where coffee is concerned, the temperature gradient is small—even on a cold day, the beverage inside the thermos is only a few dozen degrees hotter (or colder) than the air outside. In 澳门六合彩高手, the gradient is huge: with superconducting magnets cooled to a few degrees above absolute zero, the difference with the outside environment is in the range of 270 degrees Celsius.
Vacuum (an almost perfect insulator) is used in both a thermos and the 澳门六合彩高手 cryostat to provide insulation. In the first case, vacuum is sandwiched between the two "walls" of the container; in the second, the vessel itself—a ten-storey structure with a volume of 8,500 m?—is the vacuum chamber.
Part of the procurement responsibilities of India, the cryostat is being manufactured in 54 segments by Indian contractor Larsen & Toubro and shipped to the 澳门六合彩高手 Cryostat Workshop for assembly.
Over the past year and a half, we have seen the cryostat base take shape; now, work is underway simultaneously on the next section—the lower cylinder. Side by side, these components-in-progress give a true sense of the awesome size of the cryostat.
