Methods for enhancing the steady-state microbunching in storage rings.

Steady-state microbunching (SSMB) is a promising concept for generating high average power coherent radiation based on storage rings. To cover the shorter wavelength range, the bunched electron beam in conventional SSMB needs to be further compressed with advanced beam manipulation techniques. In this paper, several methods for enhancing the microbunching of SSMB have been discussed and compared. A new method termed dual-tilted-laser scheme (DTL) has been proposed. Numerical simulations with typical parameters of SSMB demonstrated that it has the potential of extending the wavelength coverage of SSMB to the EUV range based on DTL scheme with high repetition rate.
