Is “microbunching” in a free electron laser limited by the Pauli exclusion principle?

As I understand it, a free electron laser can basically be pictured as a synchrotron light source with an undulator which by the particular setup causes the electrons to self-attune so that they ...

Do accelerated particles change in size as they change in mass?

If a charged particle is accelerated to incredible energies in a particle collider, its mass increases. Does its radius increase as well and, if so, how does it compare to the change of mass? Could ...
