Description
DAΦNE, the Frascati lepton collider working at the c.m. energy of the Φ meson resonance (1020), consists of two independent rings. Each one is a quite short structure (~97 m) with many magnetic elements and no periodicity at all and is strongly affected by the detector solenoidal field (∫Bds = 2.4 Tm, to be compared with a magnetic rigidity Bρ = 1.7 Tm). As a consequence the model parameters are far from being independent from each other.
The optics model is based on beam measurements, which have been essential in remarking the collider limiting factors as well as in defining the strategy for the upgrades that have been implemented in the last years.
