99% smaller particle colliders could be possible with 50-year-old Physics trick

Researchers are developing a new particle accelerator using wakefield acceleration, which could make colliders up to 99% smaller and cheaper. This method uses plasma waves to propel particles faster than conventional electromagnetic fields. Scientists aim to build a demonstrator within a decade, potentially enabling more compact and powerful colliders by the 2050s. While not ready for the next planned collider, the technology shows promise for future upgrades and other physics applications.
