The work “Stable positron acceleration in thin, warm, hollow plasma channels” by EPP team members Thales S and Jorge V, by EPP team alumni Diana A, and collaborators in the US (Mike Downer, Mark Hogan, Vitaly Yakimenko and Rafal Zgadzaj) was recently accepted for publication in Physical Review Letters. In this work, Thales et al. propose a novel regime for positron acceleration, which may deliver high quality positron bunches free from deleterious instabilities in experiments.
