MINOS (acronym for MagIc Numbers Off Stability) is a device dedicated to perform in-flight spectroscopy of very exotic nuclei in knockout reactions. It consists of a thick liquid hydrogen target (15- 20 cm) surrounded by a TPC acting as a tracking detector. The vertex position is reconstructed from the direction of the emitted protons and the beam. In this way one can profit from the increase of luminosity (up to one order of magnitude) due to the thick target without losing resolution in the Doppler correction, as would occur if the vertex position in the target was not measured [1]. Physics experiments at the RIKEN RIBF facility have started in 2014. The approved program includes the gamma spectroscopy of very neutron rich nuclei as 52Ar, 78Ni and 110Zr, the measurement of dineutron correlation in light halo nuclei and of the invariant mass of 28O. After a description of the MINOS device, the talk will focus on recent results and future perspectives at RIBF. REFERENCES [1] A.Obertelli et al., Eur. Phys. J. A (2014) 50
