Neutrino oscillation appearance experiment using nuclear emulsion and magnetized iron

This report describes an apparatus that could be used to measure both the i dentity and charge of an outgoing lepton in a charged current neutrino inte raction. This capability in a massive detector would allow the most compreh ensive set of neutrino oscillation physics measurements. By measuring the s ix observable transitions between initial and final state neutrinos, one wo uld be able to measure all elements of the neutrino mixing matrix, as well as search for CP violation, and matter effects. If the measured matrix is n ot unitary, then one would also have an unambiguous determination of steril e neutrinos. Emulsion is considered as the tracking medium, and different t echniques are discussed for the application of a magnetic field. (C) 2000 P ublished by Elsevier Science B.V. All rights reserved.
