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.

High thermal conductivity plastics filled with graphene have high thermal conductivity and good thermal stability, and their development prospects are very broad. Besides the thermal conductivity, graphene has other excellent properties, such as high strength, high electrical and optical properties, and is widely used in mobile devices, aerospace, and new energy batteries.

One of our customers requested that we carry a thermal cycling test at extreme temperatures (between 93ºC and -178ºC) over some VIS-NIR calibration sources (five samples at a time). At the same time, these sources were tested in vacuum conditions, and electro-optical characterization at different temperatures during cycling was requested.

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.
