The production of pions in pp collisions at beam energies of ≤ 300 MeV has been studied with the COSY-TOF spectrometer, which was recently extended to flight paths of ~ 3 m for charged particles through the addition of a barrel section. Together with the bremsstrahlung channel, which was investigated in an earlier
experiment, pion production exhausts the inelastic pp cross section at these energies. TOF allows the simultaneous study of
all channels, the measurement of pnπ+ being facilitated by the neutron detector COSYnus. In this contribution, preliminary results on the pionic three-body final states are discussed.
