Description

The storage ring–based coherent light source (SRCLS) operates under extreme conditions: ultra‑low emittance, short bunches, high current, and strong damping. In such a regime, collective effects become critically important. This paper presents a preliminary study of the key collective effects in the SRCLS, including the Touschek effect, intra‑beam scattering, resistive‑wall impedance, and ion effects. Through numerical simulations and theoretical analysis, the impact of these effects on beam dynamics is evaluated. The results demonstrate that stable operation of the SRCLS can be achieved under the designed parameters.
