Suzie Sheehy chairs a discussion between accelerator physicists from across the field on what's next for particle accelerators.

Particle accelerators seem to be getting bigger, more powerful and more expensive in the quest for knowledge that helps us understand the Universe. This panel discussion at the Royal Institution brings together top researchers (including Stuart Mangles from Imperial's Plasma Physics group) to discuss the challenges in designing today's accelerators for use in answering tomorrow's research questions. Representatives of four possible future projects will discuss how and why these machines are being considered, where the major challenges lie and present their long-term vision for the future.
