Today ALPHA released the first set of results from the ALPHA-g apparatus that was added to the ALPHA setup in 2018. In a paper published in Nature today, ALPHA describes how we have observed the effect of gravity on neutral antimatter during its release from our magnetic bottle.

To get an impression of how the experiments  are done, watch the animation made by P. Traczyk and M. Brice, CERN.
