Alpha strike is a term referring to the event when an alpha particle, a composite charged particle composed of two protons and two neutrons, enters a computer and modifies the data or operation of a component in the computer. Alpha strikes can disturb the silicon substrate of the transistors in a computer through their electronic stopping power, causing the transistor to flip states if the charge imparted by the strike crosses a critical threshold (QCrit). This, in turn, can corrupt the information stored by that transistor and create a cascading effect on the operation of the component that encases it.
