Descrição: ELENA is a compact ring for cooling and further deceleration of 5.3 MeV antiprotons delivered by the CERN Antiproton Decelerator. The AD physics program is focused on trapping antiprotons in Penning traps where antihydrogen is formed after recombination with positrons. The ultimate physics goal is to perform spectroscopy on antihydrogen atoms at rest and to investigate the effect of the gravitational force on matter and antimatter. In today’s set-up, most (99.9%) of the antiprotons produced are lost due to the use ofdegrader foils needed to decelerate them from the AD ejection energy down to around 5 keV; an energy suitable for trapping. By using a ring equipped with beam cooling, high deceleration efficiency and an important increase in phase-space density can be obtained, resulting in an increased number of trapped antiprotons. For the ATRAP and ALPHA experiments, improvements of up to 2 orders of magnitude can be expected. The same holds for the AEGIS experiment which is currently b
