Registration efficiency of electrons for point sources and of delta-electrons in volume of fast ion tracks in solids

Registration of fast electron flux in solid state detector was studied. We considered spatial distributions over detector volume of three values - probability of local responses, dissipated energy and number of moving electrons. We made a definition of a registration efficiency for dissipated energy dose and for electron flux. They were calculated and compared for three cases in nuclear emulsion type-R2: plane and axial sources for a set of angles of electron emitting, and a track of fastio as a source of δ-electrons.
