The CANBERRA Cryo-Cycle™ Cryostat is a revolutionary innovation in the field of cryogenically cooled radiation detectors. This product is described as a "hybrid" cryostat because it utilizes both conventional liquid nitrogen and electric cooling. This arrangement, whereby the built-in cryocooler condenses the boil-off gas from an LN2 reservoir, provides the convenience of electric cooling and the reliability of liquid nitrogen cooling, something never seen before in this field.
