In the framework of the two proton radioactivity studies, a Time Projection Chamber was recently developed at CENBG, in order to study the correlations between the two protons emitted. In fragmentation experiments performed at LISE3/GANIL, the 2p radioactivity of 45Fe and 54Zn was directly observed with the TPC. Results on correlations between the two protons are presented and compared to a recent theoretical model.
