Description

There are two main sources of high-frequency longitudinal impedance: coherent synchrotron radiation (CSR) and high-frequency NEG-coated resistive wall impedance. They can drive microbunching instability, which is a potential risk to maintaining stable and low energy spread beam. To address this, these effects are now integrated into the particle tracking code \texttt{mbtrack2}. This paper examines their impact on beam stability in the SOLEIL~II storage ring, considering the combined influence of intrabeam scattering, low-frequency longitudinal impedance, and a harmonic cavity.
