ELENA uses e-cooling for cooling pbar beams on two plateaus at 653 keV and 100 keV kinetic energy. The first cooling is necessary to allow for efficient deceleration of the 5.3 MeV pbar beam coming from the Antiproton Decelerator (AD), while the second cooling is used to define the quality of the bunches before extraction. The experience accumulated so far shows that cooling at 653 keV is sufficient to ensure good deceleration efficiency, while cooling at 100 keV might not be sufficient to provide the design transverse beam emittances at extraction. In this paper we document the present ELENA e-cooling performance at 100 keV, the typical optimisation procedure used during setup, and we investigate possible limitations of the present system.
