GBAR Gravitational Behavior of Antihydrogen at Rest
The GBAR experiment aims to test the Equivalence Principle with antimatter by measuring the time of flight of ultra-cold antihydrogen atoms H in free fall. Antihydrogen atoms at ¯ ∼20 µK are provided by sympathetic cooling of antihydrogen ions $\bar{H}^+$ with laser cooled $Be^+$ ions. $\bar{H}^+$ i...
