We use results by Di Mitri et al. [1] as the basis of a method for suppression of synchrotron-radiation-driven beam quality degradation during recirculation. Use of second-order achromatic superperiodic recirculation transport based on individually isochronous and achromatic superperiods of low-quantum-excitation lattices is found to provide control of both emittance degradation from coherent synchrotron radiation (CSR) and microbunching instability (?BI) gain. Use of such low excitation lattices and choice of sufficiently large bend radius also insures incoherent synchrotron radiation (ISR) driven effects are well-managed.
