Laser-driven ion acceleration in the ultra-relativistic Breakout-Afterburner regime — •Shikha Bhadoria, Naveen Kumar, and Christoph H. Keitel — Max Planck Institute for Nuclear Physics, Saupfercheckweg 1, Heidelberg

Laser-accelerated ion beams have a multitude of applications with a particularly interesting one being hadron therapy that is essential for cancer treatment. Breakout-Afterburner (BOA) is one of the high-performance laser-driven-ion acceleration mechanisms capable of accelerating ions to relatively higher values with the same intensities of a laser. In this scenario, an initially opaque (overdense), ultra-thin target (with a width comparable to the laser skin depth) turns transparent to the incoming laser pulse, due to relativistically induced transparency which leads to a phase of extreme ion acceleration that is known to be aided by Buneman instability [1]. The impact of radiation reaction and Breit-Wheeler pair production on the acceleration of fully ionized Carbon ions and protons driven by an ultra-intense linearly-polarised laser pulse has been investigated in the ultra-relativistic BOA regime using multidimensional PIC simulations.
