A study of evolution of near-earth daemon's fluxes with using Dark   Electron Multipliers (DEMs)
  DEMs have been used to experimental studying the temporal evolution of the March maximum of fluxes of near-Earth daemons. It is shown that part of objects from near-Earth almost circular heliocentric orbits (NEACHOs), from which a rather intense flux proceeds during only about four weeks, forms in the second half of March the population in geocentric Earth-surface-crossing orbits (GESCOs). The resistance of the Earth's matter results in that GESCO objects sink into the Earth's interior, so that the GESCO population nearly disappears by the end of April.
