(5) defines the linear bunch compression and can be set to zero for full, linear compression by setting R56 = −1/a < 0. In this case the final bunch length will be determined by the non-linear terms and the uncorrelated energy spread. To linearize the transformation, the second term must be set to zero. 2 stores that buy designer handbags near me
