NEMESYS

Neutron Effects on MEmory SYStems

What is this about?

NEMESYS is an experimental project designed to study the effects of cosmic radiations and atmospherical events on memory systems. In particular, its aim is to correlate bit-flips in memories with strong radiation events and particles' impacts on them.

 

The experiment is supposed to participate in the REXUS/BEXUS Programme. It will be brought at high altitudes with a balloon together with several other experiments, where it will collect data about the impact of particles and cosmic radiations and eventual atmospherical events like lightnings.

Why is it important?

Reliability and safety are extremely important aspects of many critical electronic applications, such as space, avionics, and military. Sources of uncertainty must be properly studied and approached when designing electronic devices used in these fields.

 

As time flows, technology advancements let us create more and more sophisticated and small electronic devices. But the smaller the electronics become, the more they are affected by artificial and natural disturbances. Some natural events, like particles generated by extreme atmospherical conditions or cosmic radiations, still need to be better analysed and studied. Learning how they affect even simple electronic equipment like a memory device can help engineers design more reliable electronic devices we commonly use.
