In the framework of the HADES (High Acceptance DiElectron Spectrometer) collaboration the authors are developing the Time Of Flight (TOF) wall subdetector. In order to efficiently select events with e{sup +}e{sup {minus}} pairs produced in the nuclear matter, the TOF wall must be able to resolve electrons from pions up to 0.5 GeV/c and from protons up to 2 GeV/c. Because the short flight path of about 2m requires a 100--150 ps time resolution, the authors are building a granular system made of scintillator rods readout on both ends by means of photomultipliers, capable of such performance.
