Field shape of the accumulator LDA dipoles

Design of a large acceptance, high efficiency energy selection system for the ELIMAIA beam-line

“…Errors on the magnetic field coming from the design, rather than from fabrication, have been analyzed. As the design of the dipole respects the symmetry, the first error source which arise is [19]. The formalism used for the field expansion is described in [20], taking into account that the main dipole harmonic is B 1 .…”
