    Patent number: 4991399
    Abstract: A device for temporarily overcooling a detector (1) cooled permanently in a space by means of a first cooler (5).According to the invention, a second cooler (6) is temporarily made operative to produce the required overcooling without causing heat exchange with the outside.
