Design and fabrication of the compact-ERL chicane magnets

The bending magnets for the cERL chicanes are designed and fabricated to use for injecting an electron beam from an injector, ejecting the decelerated beam to its dump and adjusting the circumference of the recirculation loop. For designing these magnets, we use 2D and 3D simulation codes to establish the good field region required by the lattice and beam dynamics. As these magnets are made of electromagnetic soft iron, their magnetic properties deteriorate due to machining process. To restore them magnetic annealing is applied after the machining process. Results of the simulation and the field measurement with flip-flop coil are compared to check whether the magnets have the required magnetic properties. (author)
