Low Energy Antiproton Ring experimental area. The CPLEAR experiment used the antiproton beam of the LEAR facility – Low-Energy Antiproton Ring which operated at CERN from 1982 to 1996 – to produce neutral kaons through proton-antiproton annihilation in order to study CP, T and CPT violation in the neutral kaon system.
A proton beam will be provided by the existing GSI facility and will be further accelerated by FAIR's SIS100 ring accelerator up to 30 GeV. By the beam hitting the antiproton production target, antiprotons with a momentum of around 3 GeV/c will be produced and can be collected and pre-cooled in the Collector Ring (CR). [4]
In the second phase of the AEGIS experiment, starting from 2021 after AEgIS has been successfully connected to the new antiproton deceleration and storage ring ELENA, the Rydberg antihydrogen atoms will be channeled into a beam, which then will pass through a series of matter gratings, the central piece of a Moiré-deflectometer.
Stochastic cooling is a form of particle beam cooling. [1] It is used in some particle accelerators and storage rings to control the emittance of the particle beams in the machine. This process uses the electrical signals that the individual charged particles generate in a feedback loop to reduce the tendency of individual particles to move ...
The Antiproton Decelerator (AD) is a storage ring at the CERN laboratory near Geneva. [1] It was built from the Antiproton Collector (AC) to be a successor to the Low Energy Antiproton Ring (LEAR) and started operation in the year 2000. Antiprotons are created by impinging a proton beam from the Proton Synchrotron on a iridium target. The AD ...
It is situated inside the Antiproton Decelerator (AD) complex at CERN, Geneva. [1] [2] It is designed to further decelerate the antiproton beam coming from the Antiproton decelerator to an energy of 0.1 MeV for more precise measurements. [3] [4] The first beam circulated ELENA on 18 November 2016. [5]
A proton–antiproton collision from the UA5 experiment at the SPS in 1982 The SPS was designed by a team led by John Adams , director-general of what was then known as Laboratory II . Originally specified as a 300 GeV accelerator, the SPS was actually built to be capable of 400 GeV, an operating energy it achieved on the official commissioning ...
The Super Proton–Antiproton Synchrotron (or Sp p S, also known as the Proton–Antiproton Collider) was a particle accelerator that operated at CERN from 1981 to 1991. To operate as a proton - antiproton collider the Super Proton Synchrotron (SPS) underwent substantial modifications, altering it from a one beam synchrotron to a two-beam collider.
