This paper describes the performance and sensitivity to neutrino mixingparameters of a Magnetised Iron Neutrino Detector (MIND) at a Neutrino Factorywith a neutrino beam created from the decay of 10 GeV muons. Specifically, itis concerned with the ability of such a detector to detect muons of theopposite sign to those stored (wrong-sign muons) while suppressingcontamination of the signal from the interactions of other neutrino species inthe beam. A new more realistic simulation and analysis, which improves theefficiency of this detector at low energies, has been developed using the GENIEneutrino event generator and the GEANT4 simulation toolkit. Low energy neutrinoevents down to 1 GeV were selected, while reducing backgrounds to the $10^{-4}$level. Signal efficiency plateaus of ~60% for $\nu_\mu$ and ~70% for$\bar{\nu}_\mu$ events were achieved starting at ~5 GeV. Contamination from the$\nu_\mu\rightarrow \nu_\tau$ oscillation channel was studied for the firsttime and was found to be at the level between 1% and 4%. Full response matricesare supplied for all the signal and background channels from 1 GeV to 10 GeV.The sensitivity of an experiment involving a MIND detector of 100 ktonnes at2000 km from the Neutrino Factory is calculated for the case of $\sin^22\theta_{13}\sim 10^{-1}$. For this value of $\theta_{13}$, the accuracy in themeasurement of the CP violating phase is estimated to be $\Delta\delta_{CP}\sim 3^\circ - 5^\circ$, depending on the value of $\delta_{CP}$,the CP coverage at $5\sigma$ is 85% and the mass hierarchy would be determinedwith better than $5\sigma$ level for all values of $\delta_{CP}$.
