Abstract We report on the first production of an antihydrogen beam by charge exchange 6.1 keV antiprotons with a cloud positronium in GBAR experiment at CERN. The 100 antiproton delivered AD/ELENA facility was further decelerated pulsed drift tube. A 9 MeV electron from linear accelerator produced low energy positron beam. positrons were accumulated set two Penning–Malmberg traps. target resulted conversion extracted steered onto this to produce antiatoms. observe excess over background...

We report on the first production of an antihydrogen beam by charge exchange 6.1 keV antiprotons with a cloud positronium in GBAR experiment at CERN.The antiproton was delivered AD/ELENA facility.The target produced from positron itself obtained electron linear accelerator.We observe excess over background indicating significance 3-4 standard deviations.
