Abstract The Extra Low En­ergy An­tipro­ton stor­age ring (ELENA) is an up­grade pro­ject at the CERN AD (An­tipro­ton De­cel­er­a­tor). ELENA will fur­ther de­cel­er­ate the 5.3 MeV an­tipro­tons com­ing from the AD down to 100 keV and allow the ex­per­i­ments typ­i­cally op­er­at­ing traps to in­crease the cap­ture ef­fi­ciency. ELENA fea­tures elec­tron cool­ing for emit­tance con­trol dur­ing the de­cel­er­a­tion and there­fore pre­serve the beam in­ten­sity and to gen­er­ate bright bunches ex­tracted to­wards the ex­per­i­ments. The ring has been com­pleted with the in­stal­la­tion of the elec­tron cooler at the be­gin­ning of 2018. The elec­tron cooler is meant to op­er­ate at an elec­tron en­ergy of 355 eV and 54 eV, cor­re­spond­ing to a pbar mo­men­tum of 35 MeV/c and 13.7 MeV/c. First ob­ser­va­tions of cool­ing have been ob­served at both en­er­gies, and de­cel­er­ated ion beams with char­ac­ter­is­tics close to the de­sign val­ues have been ob­tained be­fore the start of CERN Long Shut­down 2 (LS2). The lat­est re­sults of ELENA com­mis­sion­ing will be pre­sented, to­gether with an overview of the pro­ject and sta­tus and plans.
