CBETA Schematic

Caption

Schematic of the Cornell-BNL ERL Test Accelerator. Superconducting radiofrequency (SRF) cavities accelerate electrons to high energy in stages, sending them around the racetrack-shaped accelerator after each acceleration stage. Each curved arc is made of a series of fixed field, alternating gradient (FFA) permanent magnets that can carry beams at multiple energies simultaneously. After four passes through the accelerating infrastructure and FFA arcs, the electrons then decelerate in stages, returning their energy to the SRF cavities so it can be used to accelerate electrons again.
