Description
PERLE is a multi-turn Energy Recovery LINAC, currently under construction at IJCLab in Orsay (France). It is designed to accelerate electrons of 20 mA beam current to an energy of 250 MeV through three accelerating followed by three decelerating passes to dump the beam at injection energy (7 MeV). The first order lattice design has emerged. Therefore, assessing the sensitivity of the optics to linear imperfections is a crucial step toward stable operation. This work investigates the impact of quadrupole misalignments on the beam orbit in both planes, accounting for the presence of horizontal and vertical dispersive sections in PERLE. The resulting orbit distortions are used to identify the most critical locations for diagnostics and correction elements. A correction strategy based on BPM–corrector pairs is implemented using the BMAD framework, and the achievable orbit restoration is evaluated with adequate correction strengths.
