Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
Description We successfully measured the effect of radiation reaction in the collision of an ultra intense laser with an electron beam for the first time. This has already been published in PRX and received significant media coverage.

We have also worked on understanding the exact experimental parameters that will be needed to properly distinguish between different models of this radiation reaction process.
Exploitation Route The next generation of laser labs (e.g. ELI) will be performing similar experiments to ours, pushing the intensity frontier and we are already talking with those labs on the best ways to repeat our experiment. The gamma rays have some potential in imaging of dense material and we are investigating those with DSTL

Description Our experiment which measured a process called "radiation reaction" in the collision of a high-intensity lasers with high-energy electron beams had impact outside of academia. It attracted significant attention in the online news media (published by 16 news outlets) and in social media, thereby contributing to societal impact through an increase in public awareness and knowledge of fundamental science.
