Discovery of alpha particle effects on computer chips

As an engineer, May is most noted for having solved the "alpha particle problem", which was affecting the reliability of integrated circuits as device features reached a critical size where a single alpha particle

Single event upset
A single event upset is a change of state caused by ions or electro-magnetic radiation striking a sensitive node in a micro-electronic device, such as in a microprocessor, semiconductor memory, or power transistors. The state change is a result of the free charge created by ionization in or close...
