  The Main Injector Neutrino Oscillation Search (MINOS) experiment's primary
goal is the precision measurement of the neutrino oscillation parameters in the
atmospheric neutrino sector. This long-baseline experiment uses Fermilab's NuMI
beam, measured with a Near Detector at Fermilab, and again 735 km later using a
Far Detector in the Soudan Mine Underground Lab in northern Minnesota. The
detectors are magnetized iron/scintillator calorimeters. The Far Detector has
been operational for cosmic ray and atmospheric neutrino data from July of
2003, the Near Detector from September 2004, and the NuMI beam started in early
2005. This poster presents details of the two detectors.
