Description
The ultra-low ๐ฝ๐ฆ* optics at the Accelerator Test Facility 2 (ATF2) enables studies of final focus systems under chromatic conditions relevant for future linear colliders. Following the installation of a new final doublet with improved field quality, the achievable beam size and the contribution of nonlinear aberrations are re-evaluated. Using high-order tracking with MAD-NG, the vertical beam size is decomposed into second-and third-order contributions, allowing a quantitative assessment of correction schemes based on sextupole and octupole magnets. In addition, recent emittance measurements provide realistic beam conditions for these studies. Strategies to enhance the experimental observability of octupole corrections are discussed
