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]
ATHENA, AD-1 experiment, was an antimatter research project that took place at the Antiproton Decelerator. In August 2002, it was the first experiment to produce 50,000 low-energy antihydrogen atoms, as reported in Nature. [14] [15] In 2005, ATHENA was disbanded and many of the former members worked on the subsequent 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. The ultimate goal of the experiment is to test CPT symmetry through comparing the respective spectra of hydrogen and antihydrogen. [1]
The experiment was conducted at the European Center for Nuclear Research (CERN) in Switzerland by researchers from the international Antihydrogen Laser Physics Apparatus (ALPHA) collaboration.
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. [1] [9] CERN Antimatter Factory – antiproton decelerator
The Antiproton Collector (AC) was part of the antiparticle factory at CERN designed to decelerate and store antimatter, to study the properties of antimatter and to create atoms of antihydrogen. It was built in 1986 around the existing Antiproton Accumulator (AA) to improve the antiproton production by a factor of 10.
First elements of the PUMA experiment installed in the AD facility at CERN. The PUMA (antiProton Unstable Matter Annihilation) AD-9 experiment, at the Antiproton decelerator (AD) facility at CERN, Geneva, aims to look into the quantum interactions and annihilation processes between the antiprotons and the exotic slow-moving nuclei.
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.
