  This report describes an apparatus that could be used to measure both the
identity and charge of an outgoing lepton in a charged current neutrino
interaction. This capability in a massive detector would allow the most
comprehensive set of neutrino oscillation physics measurements. By measuring
the six observable transitions between initial and final state neutrinos, one
would 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 not
unitary, then one would also have an unambiguous determination of sterile
neutrinos. Emulsion is considered as the tracking medium, and different
techniques are discussed for the application of a magnetic field.
