Sterile neutrino (${\nu }_s$) conversion in meter scale baselines can be sensitively probed using monoenergetic, sub-MeV, flavor-pure ${\nu }_e$’s from an artificial Megacurie source and the unique technology of the LENS low energy solar ${\nu }_e$ detector. Active-sterile oscillations can be directly observed in the granular LENS detector itself to critically test and extend results of short baseline accelerator and reactor experiments.
