Two-proton radioactivity is an exotic decay mode for very proton-rich nuclei. It was observed experimentally for the first time in 2002 for the nucleus {sup 45}Fe but the two protons could not be directly detected. So a new detector has been developed, a Time Projection Chamber, to individually observe the two protons emitted. It was used successfully during two experiments for the study of {sup 45}Fe and {sup 54}Zn. Energy correlations have been studied and the relative angle between the two protons is calculated.
