Hello,
I have a question about particle accelerators:  Why does there seem to be
a terminal particle energy for a given particle, accelerator, related to
the radius of the acclerator?  Is this because the radiation caused by
the fact that the article is not in an inertial frame gets too large and
approaches equilibrium state with the energy input?
Whatever the reason, is there any possibility that there exists
a yet undiscovered trick around this so that one could have an SSC type
acclerator (as far as particle energies are concerned) in a 1 meter box?
Or is this impossible in principle, given the state of physics today.

Sorry if this is too basic but a good library is far away and this may turn
out to be more fun.
