Primary goal of the AEḡIS experiment is to precisely measure the free fall of antihydrogen within Earth’s gravita-tional field. To this end, cold (≈ 50 K) antihydrogen will traverse a two-grid moiré deflectometer before annihilat-ing onto a position-sensitive detector, which shall determine …

The experimental demonstration of positronium laser cooling with stationary broadband laser pulses with negative detuning is briefly described. Considerations on the limits of the current experiment and possible future developments follow. In particular, the benefit of positron remoderation, use of a magnetic …
