Think about how a car leans when you go around a corner. That's why accelerators keep getting larger and larger to probe smaller scales at higher energies.

You mean they can't build magnets strong enough to do the business at those energies and radius of curvature of the beam ? They need to try those magnets that Wile.E.Coyote uses in the Roadrunner cartoons.

Not only that but the more powerful the bending magnets, the greater the loss of beam energy to synchrotron radiation. This is why a 7 TeV electron synchrotron would have to be a lot larger in circumference than the LHC proton synchrotron. Some electron synchrotrons are deliberately designed and built to obtain the intense synchrotron radiation. See synchrotron light source.
