The measurement of the polarization of hadrons in the few GeV energy range constitutes an important experimental challenge and allows to access unique properties of the reaction amplitudes. In particular the precise measurement of the nucleon electromagnetic form factors and the deuteron structure at short distances are accessible only through polarization observables. Our collaboration develops hadron polarimetry in Saclay (LNS) and in Dubna, in a complementary energy range. Since November 2016 a unique 10 GeV/c polarized deuteron beam is again available in Dubna, allowing a new campaign of measurements of analyzing powers for polarized protons and neutrons on different targets. We plan to organize a meeting of the ALPOM2 collaboration to discuss the consequences of the recent results for the planned JLab12 form factor experiments. It has a special meaning to organize this event in France, that is the geographical and historical meeting point, where the collaboration was formed.
