Description
After the invention of the laser in 1960, it wasn’t long until its potential use to emulate transient radiation-induced effects was recognized. Following the first experimental demonstration of this capability in 1965, a series of studies that aimed to replicate various single-event effects (SEEs) were published in quick succession. However, it wasn’t until 1987 when the first attempt to quantitatively reproduce particle-induced SEEs using laser pulses was demonstrated. Since then, attempts to correlate SEEs using a variety of methods have been steadily developed throughout the years.
In this talk, a historical overview of the various efforts to correlate laser data with ion-induced SEEs will be presented. The various studies will be examined through the lens of the main quantities used to establish an empirical correlation between laser pulse energy and the equivalent linear energy transfer (LET). The most common quantities considered for correlation in the literature are 1) SEE cross-sections, 2) collected charge measurements, 3) SEE thresholds, 4) single-event transient shapes. As will be shown, there are different levels rigor associated with the correlation resulting from the use of these different quantities.
While a universal rule for correlation remains elusive, the long history of these correlation efforts has paved the way for the development of new pulsed laser SEE techniques that aim to be predictive. These predictive techniques aim to reproduce particle-induced results in certain scenarios, without a priori knowledge of specific SEE sensitivity of a device under test. These techniques, heavily informed by past correlation efforts, represent the future of pulsed laser testing.
