FASER (ForwArd Search ExpeRiment) is one of the nine particle physics experiments in 2022 at the Large Hadron Collider at CERN.It is designed to both search for new light and weakly coupled elementary particles, and to detect and study the interactions of high-energy collider neutrinos. [1]
Bunches of usually a few 10 9 antiprotons are skimmed off the AA and then decelerated by the PS from 3.5 GeV/c to 0.6 GeV/c. [5] [6] The bunch was transferred to LEAR where it could be decelerated to a minimum 100 MeV/c or accelerated to generally 1000 MeV/c. [5] For most experiments, a "beam stretcher mode" was used, where an ultra-slow ...
[3] [4] The first beam circulated ELENA on 18 November 2016. [5] The ring is expected to be fully operational by the end of the Long Shutdown 2 (LS2) in 2021. GBAR experiment (AD-7) was the first experiment to use a beam from ELENA, with the rest of the AD experiments following suit after LS2 when beam transfer lines from ELENA will have been ...
CTF3 (CLIC Test Facility 3) was an electron accelerator facility built at CERN with the aim of demonstrating the key concepts of the Compact Linear Collider accelerator. [1] The facility consisted in two electron beamlines to mimic the functionalities of the CLIC Drive Beam and Main Beam.
Each bunch contains 2.2 × 10 8 lead ions, which are accelerated from 4.2 MeV per nucleon to 72 MeV per nucleon [7] before passing them through to the PS for storage. The most important function of LEIR is not acceleration, but electron cooling to reduce the emittance of the ion beam in order to maintain high luminosity of the final LHC beam.
The proton bunches for AWAKE are extracted from the CERN SPS and are transported through an ~800-meter beam-line to the 10-meter long vapor source of AWAKE. The electron witness bunches are injected behind the proton bunch. [4] To detect acceleration of the injected electrons, a dipole magnet is installed after the vapor, bending their path ...
The Big European Bubble Chamber (BEBC) is a large detector formerly used to study particle physics at CERN. The chamber body, a stainless-steel vessel, was filled with 35 cubic metres of superheated liquid hydrogen, liquid deuterium, or a neon-hydrogen mixture, [1] whose sensitivity was regulated by means of a movable piston weighing 2 tons ...
The process started with protons from the Super Proton Synchrotron (SPS) at CERN being fired in pulses at a carbon target to produce pions and kaons. These particles decay to produce muons and neutrinos. [1] The beam from CERN was stopped on 3 December 2012, [2] ending data taking, but the analysis of the collected data has continued.
