TY  - JOUR
AB - The dynamics of energetic particles in strong electromagnetic fields can beheavily influenced by the energy loss arising from the emission of radiationduring acceleration, known as radiation reaction. When interacting with ahigh-energy electron beam, today's lasers are sufficiently intense to explorethe transition between the classical and quantum radiation reaction regimes. Wereport on the observation of radiation reaction in the collision of anultra-relativistic electron beam generated by laser wakefield acceleration($\varepsilon > 500$ MeV) with an intense laser pulse ($a_0 > 10$). We measurean energy loss in the post-collision electron spectrum that is correlated withthe detected signal of hard photons ($\gamma$-rays), consistent with a quantum(stochastic) description of radiation reaction. The generated $\gamma$-rayshave the highest energies yet reported from an all-optical inverse Comptonscattering scheme, with critical energy $\varepsilon_{\rm crit} > $ 30 MeV.
