| Summary: | The damaging effect of coherent synchrotron radiation (CSR) on the emittance and energy spread of high-energy beams in accelerator light sources can significantly constrain the machine design and performance. We propose a mitigation approach in which the dynamical effect of the longitudinal component of CSR is suppressed by appropriately preparing the initial longitudinal current profile of the beam. In a chicane, a linear theory for the mechanism of CSR-induced emittance growth is used to demonstrate how this procedure can produce a beam whose core experiences suppressed transverse emittance growth. The dynamics of such a beam is illustrated for the Berlin-Zeuthen CSR benchmark chicane. |
