The MINOS experiment will explore neutrino oscillations in the range of par
ameter space suggested by measurements with atmospheric neutrinos. The two
magnetized toroidal tracking calorimeters, 1 kton at Fermilab and 5.4 kton
in the Soudan Mine, will be constructed out of 2.54 cm iron plates interspe
rsed with scintillator strips made in the extrusion process and will use wa
velength shifting and clear fibers read out by multi-anode photomultipliers
