Abstract
Ionisation dynamics on the nanoscale seed the processes that govern pathways to macroscopic equilibrium in irradiated matter. Therefore, understanding the conditions that underpin this transition is critical in a wide range of applications from healthcare to radiation science. Here we investigate these interactions in real time using a novel optical streaking technique that exploits the ultrafast nature and highly synchronous pump-probe capabilities of laser driven accelerators. This work reveals behaviour in the recovery of matter irradiated by protons and X-rays that can only be reconciled by considering the nanoscopic structure of the irradiated matter.
