Relativistic klystron two-beam accelerator

A high-energy linear collider consisting of two beams, a driver beam of electrons and a high-energy beam, in which the intense low-energy driver beam is bunched, is analyzed theoretically. The low-energy beam is made to travel through resonant transfer cavities, in which it radiates microwave energy that is used to accelerate the second beam to very high energies. The low-energy beam is maintained at a constant energy by periodic induction acceleration cavities.
