Neutron beam monitoring for single-event effects testing
… testing of electronics against neutron-induced single event effects (SEEs). The system can measure the transmission along the neutron beam line where several devices are tested simultaneously, allowing beam degradation by upstream experiments to be taken into account. In signal processing, the …

Characterizing the influence of neutron fields in causing single-event effects using portable detectors
… devices caused by cosmic rays is known as Single Event Effects(SEEs). In the atmosphere, secondary neutrons are the dominant particles causing this effect. The neutron flux density in atmosphere is very low. For a good statistical certainty, millions of device hours are required to measure …
