AccueilCESAR: Cryogenic Electronics for Space Applications and Research
Observations from space provide real benefits in many scientific fields, like astrophysics.
They allow to significantly improve the spectral information compared to ground-based observations.
The CESAR project funded by the European Union is a collaborative project under the Seventh Framework Program (FP7). COORDINATOR : Commissariat à l'Energie Atomique et aux Energies Alternatives (CEA), France EU FP7 Contract no : 263455 Duration : 36 months
To carry out these observations, many laboratories are developing new generation ultra-sensitive sensors.
The space environment is a major challenge for the development of cryogenic electronics associated with these sensors.
The CESAR project explores new solutions in this area.
