PERLE (Powerful Energy Recovery LINAC for Experiment) is a high-power Energy Recovery
LINAC (ERL) facility with 20 mA beam current and beam energy from 250 MeV to 500 MeV
featuring three passes through two cryomodules. It is a hub for validation of the ERL technology
development towards future energy and intensity frontier machines. Design challenges of PERLE
and its beam parameters make it a testbed to validate multi-turn high current ERL operation for
the LHeC. It will be the first ERL for some pioneering experiment of the eN interaction with
radioactive nuclei.
In this work, design and optimization of the commutational magnet (B-com) used to
spread/combine the three beams and one series of the quadrupole magnet is proposed. It gives the
design parameters including: yoke geometry, pole profile, and material, and calculation of the
excitation current needed to drive the magnet, the coil parameters and the number of turns.
The B-com magnet is optimized for a 30° bending angle with magnetic field of 0.88 T along the
magnet length and a harmonic content of 0.036%. The quadrupole magnet is designed for a
gradient field of 34.15 T/m and experience a saturation above this value. Further studies to avoid
saturation and achieve the maximum gradient of 44.1 T/m required by the beam dynamics is
undergoing.
