The lowest cryogenic temperatures achievable with liquid nitrogen systems are 77K. To lower temperatures further, it is necessary to use other systems. Helium cryostats can use this noble gas to cool a plate and reach temperatures of 4K. All these processes must be done in a vacuum since the air doesn’t allow the temperature.

A space simulation system, developed entirely by the Optoelectronic department, has been implemented for some time. This system has managed to reach pressure values of 10-7mbar and temperatures between -100ºC and 150ºC. Thanks to the new cryogenic shielding shroud, it can absorb the equipment’s infrared radiation and achieve a great thermal homogeneity.

Monitoring of JUICE Optical Fibers During Thermal Cycles Keeping the Optical Connectors at Different Stable Cryogenic Temperatures in 3-Chambers Setup Two types of multimode fibers (50µm and 400µm) will be used for the scalar sensor of the JUICE (Jupiter Icy Moon Explorer program) magnetometer. This optical sensor will be placed at the end of a boom. These multimode fibers will transmit modulated laser light through the sensor, the light source, and the detector electronics being located within the spaceship.
