Copper cube cryostat

Copper cube cryostat – Italian researchers from the Institute of Nuclear Physics (INFN). Put the copper cube with a volume of 1 and 400 kg in a special cryostat designed so that extremely cool down items. This is the first cryostat, which maintains the temperature course barely above the absolute zero (0 Kelvin = -273.15 ° C). In the case of copper cube thermometer stopped just 6 milikelwinach, or 0.006 degree above absolute zero.
