Massive Observatory for Neutrino Oscillation or Limits on Their existence (
MONOLITH) is the project of an experiment to study atmospheric neutrino osc
illations with a massive magnetized iron detector. A 8 t prototype equipped
with about 20 m(2) of Glass RPGs has been realized and tested at LNCS with
cosmic-ray muons. The capability to determine the muon direction, by means
of the time-of-flight technique, is discussed. (C) 2001 Elsevier Science B
