Abstract

Linac optics of an energy recovery linac (ERL) is optimized to ensure the high average current electron beam to drive synchrotron light sources and free-electron lasers. Genetic algorithm is utilized to search globally optimum parameters of the linac optics. Multi-pass transverse beam-break-up (BBU) threshold current is estimated by numerical simulation with the optimized optics parameters. It is shown by numerical simulations that over 100 mA of multi-pass transverse BBU threshold current can be achieved in a simple one-pass ERL with cavity gradient of less than 15 MV/m
