A new path toward gravity experiments with antihydrogen

We propose to use a 13 KeV antiproton beam passing through a dense cloud of positronium (Ps) atoms to produce an H + "beam". These ions can be slowed down and captured by a trap. The process involves two reactions with large cross sections under the same experimental conditions: the interaction of p with P S to produce H and the e + capture by H reacting on P S to produce H + . The decelerated H + ions are captured and cooled in a trap. The extra e + is removed with a laser to measure the
