Query: Optimization of a Very Low Energy Neutrino Factory for the Disappearance
  Into Sterile Neutrinos   We discuss short-baseline electron and muon neutrino disappearance searches
into sterile neutrinos at a Very Low Energy Neutrino Factory (VLENF) with a
muon energy between about two and four GeV. A lesson learned from reactor
experiments, such as Double Chooz and Daya Bay, is to use near and far
detectors with identical technologies to reduce the systematical errors. We
therefore derive the physics results from a combined near-far detector fit and
illustrate that uncertainties on cross sections x efficiencies can be
eliminated in a self-consistent way. We also include the geometry of the setup,
i.e., the extension of the decay straight and the muon decay kinematics
relevant at the near detector, and we demonstrate that these affect the
sensitivities for Delta m^2 > 30 eV^2, where oscillations take place already in
the near detector. Compared to appearance searches, we find that the
sensitivity depends on the locations of both detectors and the muon energy,
where the near detector should be as close as possible to the source, and the
far detector at about 500 to 800m. In order to exclude the currently preferred
parameter region, at least 10^19 useful muon decays per polarity are needed for
E_mu=2 GeV, or, alternatively, a higher muon energy can be used.
