In this new MBA concept, two pairs of dispersion bumps are created in each cell, which accommodate sextupoles to correct chromaticities. For each pair of dispersion bumps, from the point of view of two different representations of a cell, many nonlinear effects caused by itself are cancelled out within one cell. For the two pairs of dispersion bumps, from the nonlinear cancellation point of view, they are interleaved. Compared to the hybrid MBA where only one pair of dispersion bumps is created in each cell, this new MBA can provide more knobs so as to better control tune shift terms, which is especially beneficial for enlarging dynamic momentum aperture.
