Directional sensitivity to nuclear recoils would provide a smoking gun for a possible discovery of dark matter in the form of WIMPs Weakly Interacting Massive Particles,. A hint of directional dependence of the response of a dual-phase argon Time Projection Chamber was found in the SCENE experiment. Given the potential importance of such a capability in the framework of dark matter searches, a new dedicated experiment, ReD Recoil Directionality,, was designed by the Global Argon Dark Matter Collaboration, in order to scrutinize this hint. Before the irradiation with a neutron beam, the ReD TPC underwent a long campaign of characterization and optimization: some selected results are presented in this contribution.
