TOF (Time of Flight)

• Extraction of a 24 GeV/c proton bunches from PS
  onto lead target installed in the TT2 tunnel. The
  neutrons produced by spallation will be canalised
  to an experimental area located 200 m downstream
  throughout a vacuum pipe making use of the
  existing T2A tunnel about 7 m below the ISR tunnel
