AEgIS (Antimatter Experiment: gravity, Interferometry, Spectroscopy), AD-6, is an experiment at the Antiproton Decelerator facility at CERN.Its primary goal is to measure directly the effect of Earth's gravitational field on antihydrogen atoms with significant precision. [1]
AEgIS, Antimatter Experiment: gravity, Interferometry, Spectroscopy, AD-6, is an experiment at the Antiproton Decelerator. AEgIS would attempt to determine if gravity affects antimatter in the same way it affects normal matter by testing its effect on an antihydrogen beam.
GBAR (Gravitational Behaviour of Anti hydrogen at Rest), AD-7 experiment, is a multinational collaboration at the Antiproton Decelerator of CERN. The GBAR project aims to measure the free-fall acceleration of ultra-cold neutral anti-hydrogen atoms in the terrestrial gravitational field .
These limits were coarse, with a relative precision of ±100%, thus, far from a clear statement even for the sign of gravity acting on antimatter. Future experiments at CERN with beams of antihydrogen, such as AEgIS, or with trapped antihydrogen, such as ALPHA and GBAR, have to improve the sensitivity to make a clear, scientific statement about ...
This results in a loss of about 99.9% of antiprotons. The ELENA ring with its efficient beam cooling and deceleration method is meant to increase the effective number of antiprotons that could be made available to the antimatter experiments by reducing the usage of the degrader foils.

ALPHA experiment. The Antihydrogen Laser Physics Apparatus (ALPHA), also known as AD-5, is an experiment at CERN's Antiproton Decelerator, designed to trap antihydrogen in a magnetic trap in order to study its atomic spectra.
ATHENA, also known as the AD-1 experiment, was an antimatter research project at the Antiproton Decelerator at CERN, Geneva.In August 2002, it was the first experiment to produce 50,000 low-energy antihydrogen atoms, as reported in Nature.
The main scope of the Antiproton Collector (AC) was to increase the antiproton luminosity in CERN's accelerator complex. Upgrading to the AC increased the number of available antiprotons tenfold to around 4.5 × 10 9 antiprotons per second. The reason for this was the much larger acceptance of the AC compared to the Antiproton Accumulator (AA ...
