  Recent measurements of large theta_{13} by Daya Bay and RENO reactor
experiments have opened up the possibility of determining the neutrino mass
hierarchy, i.e. the sign of the mass squared splitting Delta m_{31}^2, the
CP-violating phase delta_{CP} and the octant of theta_{23}. In the light of
this result, we study the performance of a low energy neutrino factory (LENF)
for determination of the mass hierarchy. In particular, we explore the
potential of the nu_e$ and bar{\nu}_e disappearance channels at LENF to
determine the neutrino mass hierarchy, that is free from the uncertainties
arising from the unknown delta_{CP} phase and the theta_{23} octant. We find
that using these electron neutrino (antineutrino) disappearance channels with a
standard LENF, it is possible to exclude the wrong hierarchy at 5 sigma with
only 2 years of running.
