AD-7/GBAR status report for the 2023 CERN SPSC
We report on the activities performed during 2022 and the plans for 2023 for the GBAR experiment
Production of antihydrogen atoms by 6 keV antiprotons through a positronium cloud
International audienceWe report on the first production of an antihydrogen beam by charge exchange of 6.1 keV antiprotons with a cloud of positronium in the GBAR experiment at CERN. The antiproton beam was delivered by the AD/ELENA facility. The positronium target was produced from a positron beam itself obtained from an electron linear accelerator. We observe an excess over background indicating antihydrogen production with a significance of 3-4 standard deviations
