Description
The Swiss Light Source upgrade, SLS 2.0, is a next-generation storage ring featuring an ultra-low-emittance lattice based on a seven-bend achromat design. Achieving such low emittance requires strong focusing, which in turn generates large negative chromaticities. These are corrected using powerful sextupole magnets, introducing nonlinear effects in the beam dynamics. In particular, amplitude-dependent tune shifts (ADTS) and chromatic tune shifts (CTS) play a significant role. This contribution presents measurements of ADTS and CTS performed using high-precision tune measurements. Furthermore, since SLS 2.0 comprises 12 sectors equipped with 22 octupoles each, the control of ADTS and CTS through the use of octupoles is demonstrated.
