Relativistic Collective Effect Accelerator to Reach Ultrahigh Energies

A collective circular particle accelerator is proposed, with the potential to reach ultrahigh particle energies, including large luminosities. In the accelerator an electron cloud is produced within a large toroidal magnetic solenoid by inductive charge injection through the action of a travelling magnetic wave running around the torus. At the same time, the travell ing magnetic wave accelerates the electron cloud to relativistic energies. By continuous inductive charge injection the cloud can be relativistically densified and the thusly densified cloud becomes the source of ultrastrong electric and magnetic fields, many times stronger than is possible using only externally applied fields. These large fields can then be used to keep ions in a circular orbit, and an accelerator with a circumference of 10 km could accelerate protons up to 103 TeV with luminosities up to 1033 cm-2sec-1.
