Characterisation of the MAX II storage ring lattice

Several unconventional accelerator technology solutions were introduced in the MAX II electron storage ring during the 1990s, such as quadrupole magnets with integrated sextupoles, non-zero dispersion in the straight sections and a common girder for all magnets in the same cell. The lattice of the MAX II ring has been characterised in order to evaluate these solutions, to assist in MAX II operation and in preparation of the planned MAX IV project. Characterisation was done primarily through a combination of response matrix analysis and transverse and longitudinal beam size measurements, with additional dispersion and tune measurements.
