"SRF Linacs for High Brilliance Compact X-ray Sources and Mergers for Magnetized Beams"

Abstract:   In recent years, there is an interest in using inverse Compton scattering for compact X-ray sources of high flux and brilliance in a narrow bandwidth. An appropriate compact, superconducting accelerator for such a light source has been designed, which is capable of producing an extremely small emittance and spot size at the scattering point. The design and beam dynamics simulation results are presented, along with performance estimates of a high average brilliance light source using this beam.

One of the most challenging design aspects of any energy recovery linac is the merger. It becomes even more challenging when the beam is highly sensitive to non-axially symmetric transport, which is true of magnetized beams. Magnetized beams are canonical angular momentum dominated beams which occur when a solenoid magnetic field is applied to the cathode. Simulation results are presented for a number of mergers, focusing on the "Straight" Merger. The "Straight" Merger features a dipole magnetic field superimposed on an RF deflecting cavity, a concept which was recently tested at CBETA.
