OK, maybe we can't get 20 TeV electrons into a meter even without
synchrotron radiation. However, although I'm a lowly atomic physicist
everyone I talk to in particle physics would prefer to look for new
particles with e+e- colliders, and there the practical limitation _is_
synchrotron radiation. The only reason to use protons, I'm told, is

1) to study proton structure

2) to avoid synchrotron losses

By the way, I can make my coffee cup move in a 1-meter circle at millions
of TeV with no difficulty (a million TeV = 0.1 Joule) so the only problem
with Buicks is making them small enough.
