Airbus tests integrated circuits for satellites at the ESRF

When satellites are sent to outer space, they become under considerable stress through galactic cosmic rays and solar particles. The electronic components used inside satellites can malfunction if they are not robust enough to these ionizing particles.

Until now, engineers from AIRBUS have tested these components in cyclotron facilities, under heavy ions. Most of the cyclotrons provide high LET (Linear Energy Transfer) heavy ions not capable to penetrate through significant thickness of materials. “As technology develops, we create more complex chips, which contain active layers that can be very different to each other, and traditional cyclotrons can’t access the buried layers”, explains Cecile Weulersse, researcher at AIRBUS…
