particle identification method for the HERMES experiment. The time-of-flight is
measured by two 1x4 m^2 scintillation hodoscopes that initially were designed
for the first-level trigger only. However, the suitable time structure of the
HERA electron beam allows an extension of their functions to also measure the
TOF for low momentum hadron identification. Using only these conventional
hodoscopes, good particle identification was achieved for protons and pions in
the momentum range up to 2.9GeV/c and for kaons up to 1.5GeV/c.
