The dynamic apertures (DAs) for 1000 turns at the center of the injection straight where βx = 19.8 m and βy = 2.4 m. The solid red curve and dashed curves are on-momentum DAs for an ideal ring without errors and for the ring with sextupole misalignment of σ = 15 µm r.m.s. with the cutoff at ±2σ, respectively. Off-momentum DAs for ±3% are also shown (orange and light blue). The energy oscillation is taken into account by turning on the RF voltage at 5 MV. |
