What is LhARA?

Half of all successful cancer treatments use radiotherapy, and researchers are continually developing new approaches. LhARA is exploring the development of laser-driven particle beams, a technology that could enable smaller, more affordable, and more widely available advanced radiotherapy facilities worldwide. We're an international collaboration of physicists, biologists, clinicians and engineers exploring how lasers could give doctors new options in the fight against cancer.
