  Physics cases of increasing interest in the recent years, such as the study
of double charge exchange reactions for neutrino physics, require the study of
very suppressed reaction channels in medium-heavy ion induced nuclear
reactions. The main experimental challenges are the possibility to identify and
detect the medium-heavy quasi-projectiles and the capability to measure very
low cross-sections (few nb) with high sensitivity at very forward angles,
including zero degree. The experimental techniques adopted in the setup of the
MAGNEX magnetic spectrometer to face these issues are described in this paper.
