  Fast longitudinal beam accumulation has been demonstrated in the ESR at GSI with an Ar18+ beam coming from the synchrotron SIS18 at 400 MeV/u. Continuous application of stochastic cooling in all three phase space directions, merges the stack with the new injected bunch. Longitudinal beam compression was achieved by using either short barrier bucket rf pulses or by successive injections onto the unstable fixed point of the rf bucket at h=1. This recent experiment in the ESR provides the proof of principle for the planned longitudinal stacking of pre-cooled antiprotons in the HESR, injected from the CR.
