PBPL research covers a wide range of beam dynamics and acceleration methods; beam-radiation interaction and productions; beam-plasma interactions; beam-matter interactions and diagnostics. Our work includes the creation of ultra-fast, high-brightness electron beams; the application of such beams to advanced accelerators using lasers and/or plasmas; the creation of new types of light sources, such as free-electron lasers and inverse-Compton scattering sources based on high brightness electron beams.
