In this letter, I describe a scheme for beam stacking in a storage ring using barrier buckets without any emittance dilution to the majority of the beam. First I discuss the general principle of the method "longitudinal phase-space coating". This scheme has been convincingly validated by multi-particle 2D-beam dynamics simulations and has been demonstrated with beam experiments at the Fermilab Recycler. We also present its usefulness in mapping the incoherent synchrotron tune spectrum of beam particles in barrier buckets and to produce a clean hollow beam in longitudinal phase space. The beam stacking scheme presented here is the first of its kind.
