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]
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 ...
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.
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.
Simon van der Meer in the Antiproton Accumulator Control Room, 1984. From the beginning of the project, the potential of physics with low-energy antiprotons was recognized. A Low Energy Antiproton Ring (LEAR) was built and received antiprotons from the AA from 1983 on, for deceleration to as low as 100 MeV/c. [8] The first artificially created antimatter, in the form of anti-Hydrogen, was ...
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.
A vacuum is defined as a space with as little energy in it as possible. Despite the name, the vacuum still has quantum fields.A true vacuum is stable because it is at a global minimum of energy, and is commonly assumed to coincide with the physical vacuum state we live in.
