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.
FAQ from CERN with information about antimatter aimed at the general reader, posted in response to antimatter's fictional portrayal in Angels & Demons; What is direct CP-violation? Animated illustration of antihydrogen production at CERN from the Exploratorium. "Mining for Neutrinos", costly experiment to study neutrinos & anti-neutrinos.
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]
In showing that antimatter and matter are gravitationally attracted, the experiment ruled out one possible explanation for antimatter's scarcity - that it was gravitationally repelled by matter ...
The experiment is a recognized CERN experiment (RE1). [5] [6] The module is a detector that measures antimatter in cosmic rays; this information is needed to understand the formation of the universe and search for evidence of dark matter. The principal investigator is Nobel laureate particle physicist Samuel Ting.
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. The ultimate goal of the experiment is to test CPT symmetry through comparing the respective spectra of hydrogen and antihydrogen. [1]
The Low Energy Anti-Proton Ring (LEAR) was a particle accelerator at CERN which operated from 1982 until 1996. [1] The ring was designed to decelerate and store antiprotons, to study the properties of antimatter and to create atoms of antihydrogen. [2]
Antihydrogen ( H) is the antimatter counterpart of hydrogen.Whereas the common hydrogen atom is composed of an electron and proton, the antihydrogen atom is made up of a positron and antiproton.
