Traditional cryogenic vibration isolators require elements in contact to isolate the suspended mass. Potential creep, plasticity or permanent elongation issues limit the number of times that these systems can be rebooted thermally. In addition, conducted heat coming from ground compromises the performance of suspended optic and electronic devices. To provide passive vibration isolation and to eliminate heat conducted between the external interface and the suspended mass, a Superconducting Magnetic Suspension (SMS) has been developed by a consortium led by MAG SOAR. The lack of contact makes conduction of heat to be zero. An additional advantage of the SMS is that the energy is dissipated on ground and consequently does not influence the suspended mass. Individual test results have shown that the technology is a promising candidate to future cryogenic space instruments [1]. Based on the lessons learn during the component design, four components have been designed and manufactured at MAG SOAR facilities to support a 12 kg Focal Plane Array (FPA) in cryogenic space-based instruments. An example of a mission utilizing a cryogenic FPA would be the planned X-ray observatory ATHENA. The vibration isolator and thermal disconnect can be scale up and re-design depending of the desired suspended mass. |
