Description

PERLE (Powerful Energy Recovery Linac for Experiments) is a multi-turn, high-current energy-recovery linac under development at IJCLab, designed to operate at 20~mA and 250~MeV.
To limit beam-induced losses in downstream superconducting sections, halo particles must be intercepted at low energy.
In this work, halo cleaning in the merger is studied using a 6D particle distribution obtained after the booster stage, at 7~MeV.
The beam phase-space evolution is analyzed to identify optimal locations for one or two collimators.
Particle tracking simulations performed with the Bmad code are used to validate the collimation strategy and quantify its efficiency.
Despite the low dispersion in the merger, correlations between transverse and off-momentum halo enable partial removal of off-momentum particles.
The sensitivity of the collimation efficiency to booster cavity misalignments is also investigated.
