Online optimisation of the MAX IV 3 GeV storage ring octupoles
(2023) In Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment 1046.- Abstract
The MAX IV 3 GeV storage ring lattice contains three separate families of octupole magnets. During the lattice design, they served the purpose of minimising the amplitude-dependent tune shift. Ensuring the optimal settings of the octupoles is important in order to achieve the desired machine performance in terms of transverse dynamic acceptance and momentum acceptance. This paper describes the online optimisation process used to find octupole settings which improve the Touschek lifetime, and better recreate the desired amplitude-dependent tune shift, as well as their effect on transverse dynamic acceptance and momentum acceptance.
