Moore’s Law for Lawrence’s Device: Shrinking the Particle Accelerator

March 23, 2021

As Moore’s law continues to push forward semiconductor devices, we are now seeing commercial devices with feature sizes below 5 nanometers. Through the use of high power, short pulse lasers, a technology which warranted the 2018 Nobel Prize in Physics, an analogous revolution is set to occur in particle accelerators. These new laser driven accelerators can achieve efficient acceleration of particles and generate bright x-rays with a potential to shrink the size and cost of the device, opening new applications which were not practical before. We will discuss the science behind using light to accelerate particles, and some of the applications now possible.
