Description
Laser-plasma accelerators hold great promise for a range of radiation generation applications due to their high accelerating gradients, which can result in significant reductions in facility size and cost. They are also capable of producing electron beams with novel and tunable properties, including ultrashort bunch durations. Recent work has demonstrated several advances in secondary radiation generation, achieving high performance with stable operation over extended periods.
This talk will present an overview of recent breakthroughs in compact radiation sources based on laser-plasma accelerators at the BELLA Center, Lawrence Berkeley National Lab. Highlights include stable, high-gain operation of compact free-electron lasers over several hours (S. Barber et al., PRL 2025; F. Kohrell et al., PRAB submitted; K. Jensen et al., PRAB submitted), compact generation of directional multi-GeV muon beams (D. Terzani et al., PRAB 2025), Thomson scattering for monochromatic gamma-ray production (H.-E. Tsai et al., PRAB in prep), and advanced imaging applications using LPA betatron radiation (M. Balcazar et al., Nature Communications 2025).
