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.

The manufacture and testing of EEE parts designed for the Space market are complex procedures that strict specification systems have ruled for years. These specifications depend on various factors such us, country of origin of the parts (USA, European, Japan…), use the parts were designed for (Space, Military) and the component’s family (resistors, capacitors, inductors, microcircuits…).

What does Electrothermal events in Crimped Connectors refer to?

Electrothermal events. Electrothermal event refers to abnormal temperature increase leading to malfunction or catastrophic fails. The high temperature reached during such event activates or initiates some of the failure mechanism explained before, such as the growth of insulation oxide layers and outgassing processes responsible for organic contamination. Besides the formation of nonconductive layers at the contact interface, high temperature can also cause to the degradation of plastic insulators and contribute to multiple short circuit conditions.

Once the pre-procurement and procurement activities have been considered, the project manager and the different team members will ensure that the whole process to validate commercial components is performed accordingly in a timely manner.

Pre-Procurement

The pre-procurement phase combines the EEE parts state-of-the-art analysis, risk analysis and component ownership cost optimization with regards to the mission requirements, design criticality and budget. In order to achieve this, the project manager leading a multidisciplinary team must find the optimal balance between component information availability (traceability, materials, testing, previous use…) and minimum tests to perform, reaching an acceptable level of reliability covering the technical, schedule and costing constraints.
