-In the focus mode, the maximum momentum acceptance is achieved (±2%) by making the analysis line achromatic with a maximum dispersion value 1.5 cm/% reached at the intermediate image plane (see [[Fig. xxx]]). In this mode the coordinates of the fragment at the spectrograph focal plane are sensitive to the momentum of the beam impinging on the target. The momentum of each particle beam must then be tracked, significantly limiting the resolution at the focal plane to about 1 part in 1000 in energy. +In the focus mode, the maximum momentum acceptance is achieved (±2%) by making the [[Introduction#Analysis line|analysis line]] achromatic with a maximum dispersion value 1.5 cm/% reached at the intermediate image plane (see [[Fig. xxx]]).
