Query: Extracting Matter Effects, Masses and Mixings at a Neutrino Factory   We discuss and quantify different possibilities to determine matter effects,
the value and the sign of $Delta m^2_{31}$, as well as the magnitude of $\sin^2
2\theta_{13}$ in very long baseline neutrino oscillation experiments. We study
neutrino oscillation at a neutrino factory in the $\nu_\mu\to\nu_\mu$
disappearance and $\nu_e\to\nu_\mu$ appearance channels with and without muon
charge identification. One possibility is to analyze the $\nu_e\to\nu_\mu$
appearance channels leading to wrong sign muon events, which requires however
very good muon charge identification. Without charge identification it is still
possible to operate the neutrino factory both with $\mu^-$ and $\mu^+$ beams
and to analyze the differences in the total neutrino event rate spectra. We
show that this leads already to a quite good sensitivity, which may be
important if right sign charge rejection capabilities are insufficient. With
muon charge identification one can study the $\nu_\mu\to\nu_\mu$ disappearance
and the $\nu_e\to\nu_\mu$ appearance channels independently. The best method is
finally achieved by combining all available information of the
$\nu_\mu\to\nu_\mu$ disappearance and $\nu_e\to\nu_\mu$ appearance channels
with charge identification and we show the sensitivity which can be achieved.
