最近推荐的实验GBAR预计将在欧洲核子研究中心的AD/Elena反质子源上进行。它的目标是通过观察反氢原子的自由落体来首次测量地球对反物质的重力加速度。这需要以前所未有的低能量创造反原子。对实验的不同步骤及其现状进行了综述。
The recently recommended experiment GBAR is foreseen to run at CERN at the AD/ELENA antiproton source. It aims at performing the first measurement of the Earth's gravitational acceleration on antimatter by observing the free-fall of antihydrogen atoms. This requires creating anti-atoms at an unprecedented low energy. The different steps of the experiment and their present status are reviewed.
