The Limits of Magnet Technology

New technology could let you get away with faster velocities without having gigantic tunnels and these superconducting magnets. The idea is instead of making the magnet stronger, can we make the accelerator part much more powerful? And so one idea is to use a plasma instead of having a vacuum. You take this plasma and you like zap it with a laser, which rearranges all the charges within the plasma in such a way to create very strong electric fields inside the plasma that can be used to accelerate particles.
