Coherent synchrotron radiation (CSR) in dipoles can degrade beam quality by increasing energy spread and transverse emittance. A simple one-dimensional CSR-kick model was developed to analyze CSR effects derive conditions for suppression [Jiao ]. However, this assumes a constant bunch length within the dipole, limiting its accuracy scenarios involving compression, where typically varies. This limitation requires numerical corrections, which may reduce general applicability of model. We...
