Zimeysa railway station

Meyrin (French pronunciation: ​[mɛʁɛ̃]) is a municipality of the Canton of Geneva, Switzerland. The main site of CERN, the European particle physics research organisation, is in Meyrin. Meyrin was originally a small agricultural village until the 1950s, when construction of CERN began just to the north. It is now a commuter town dominated with apartment high-rises, and many of its residents work at CERN or in central Geneva. Geneva International Airport is partially located within Meyrin.

Meyrin railway station (French: Gare de Meyrin), formerly known as Vernier-Meyrin, is a railway station in the municipality of Meyrin, in the Swiss canton of Geneva. It is an intermediate stop on the standard gauge Lyon–Geneva line of Swiss Federal Railways.

The Globe of Science and Innovation is a visitor center, designed to inform visitors about the significant research being carried out at CERN. The wooden structure, which is 27 metres (89 ft) high and 40 metres (130 ft) in diameter, is a symbol of planet earth and was originally built for Expo.02 in Neuchâtel, Switzerland. In 2004, it was moved to its current location in Meyrin in the Canton of Geneva, Switzerland.

The Synchro-Cyclotron, or Synchrocyclotron (SC), built in 1957, was CERN’s first accelerator. It was 15.7 metres (52 ft) in circumference and provided beams for CERN's first experiments in particle and nuclear physics. It accelerated particles to energies up to 600 MeV. The foundation stone of CERN was laid at the site of the Synchrocyclotron by the first Director-General of CERN, Felix Bloch. After its remarkably long 33 years of service time, the SC was decommissioned in 1990. Nowadays it accepts visitors as an exhibition area in CERN.

ATLAS is the largest general-purpose particle detector experiment at the Large Hadron Collider (LHC), a particle accelerator at CERN (the European Organization for Nuclear Research) in Switzerland. The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators. ATLAS was one of the two LHC experiments involved in the discovery of the Higgs boson in July 2012. It was also designed to search for evidence of theories of particle physics beyond the Standard Model. The experiment is a collaboration involving 6,003 members, out of which 3,822 are physicists (last update: June 26, 2022) from 257 institutions in 42 countries.

MoEDAL (Monopole and Exotics Detector at the LHC) is a particle physics experiment at the Large Hadron Collider (LHC).

FASER (ForwArd Search ExpeRiment) is planned to be one of the eight 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 study the interactions of high-energy neutrinos.The experiment is installed in the service tunnel TI12, which is 480 m downstream from the interaction point used by the ATLAS experiment. This tunnel was formerly used to inject the beam from the SPS into the LEP accelerator. In this location, the FASER experiment is placed into an intense and highly collimated beam of both neutrinos as well as possible new particles. Additionally, it is shielded from ATLAS by about 100 meters of rock and concrete, providing a low background environment. The FASER experiment was approved in 2019 and will start taking data during Run 3 of the LHC, starting in 2022.

The LHCf (Large Hadron Collider forward) is a special-purpose Large Hadron Collider experiment for astroparticle (cosmic ray) physics, and one of eight detectors in the LHC accelerator at CERN. The other seven are: ATLAS, ALICE, CMS, MoEDAL, TOTEM, LHCb and FASER. LHCf is designed to study the particles generated in the "forward" region of collisions, those almost directly in line with the colliding proton beams. It therefore consists of two detectors, 140 m on either side of the interaction point. Because of this large distance, it can co-exist with a more conventional detector surrounding the interaction point, and shares the interaction point IP1 with the much larger general-purpose ATLAS experiment.

The European Organization for Nuclear Research, known as CERN (; French pronunciation: ​[sɛʁn]; Conseil Européen pour la Recherche Nucléaire), is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in a northwestern suburb of Geneva, on the France–Switzerland border. It comprises 23 member states, and Israel (admitted in 2013) is currently the only non-European country holding full membership. CERN is an official United Nations General Assembly observer.The acronym CERN is also used to refer to the laboratory; in 2019, it had 2,660 scientific, technical, and administrative staff members, and hosted about 12,400 users from institutions in more than 70 countries. In 2016, CERN generated 49 petabytes of data.CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research — consequently, numerous experiments have been constructed at CERN through international collaborations. CERN is the site of the Large Hadron Collider (LHC), the world's largest and highest-energy particle collider. The main site at Meyrin hosts a large computing facility, which is primarily used to store and analyze data from experiments, as well as simulate events. As researchers require remote access to these facilities, the lab has historically been a major wide area network hub. CERN is also the birthplace of the World Wide Web.

Deutsche Schule Genf (DSG; French: École Allemande de Genève) is a German international school in Vernier, Switzerland, in the Geneva metropolitan area. It serves levels Kindergarten through Sekundarstufe II (Oberstufe).

The ISOLDE (Isotope Separator On Line DEvice) Radioactive Ion Beam Facility, is an on-line isotope separator facility located at the centre of the CERN accelerator complex on the Franco-Swiss border. Created in 1964, the ISOLDE facility started delivering radioactive ion beams (RIBs) to users in 1967. Originally located at the Synchro-Cyclotron (SC) accelerator (CERN's first ever particle accelerator), the facility has been upgraded several times most notably in 1992 when the whole facility was moved to be connected to CERN's ProtonSynchroton Booster (PSB). ISOLDE is currently the longest-running facility in operation at CERN, with continuous developments of the facility and its experiments keeping ISOLDE at the forefront of science with RIBs. ISOLDE benefits a wide range of physics communities with applications covering nuclear, atomic, molecular and solid-state physics, but also biophysics and astrophysics, as well as high-precision experiments looking for physics beyond the Standard Model. The facility is operated by the ISOLDE Collaboration, comprising CERN and sixteen (mostly) European countries. As of 2019, close to 1,000 experimentalists around the world (including all continents) are coming to ISOLDE to perform typically 50 different experiments per year.Radioactive nuclei are produced at ISOLDE by shooting a high-energy (1.4GeV) beam of protons delivered by CERN's PSB accelerator on a 20 cm thick target. Several target materials are used depending on the desired final isotopes that are requested by the experimentalists. The interaction of the proton beam with the target material produces radioactive species through spallation, fragmentation and fission reactions. They are subsequently extracted from the bulk of the target material through thermal diffusion processes by heating the target to about 2,000 °C.The cocktail of produced isotopes is ultimately filtered using one of ISOLDE's two magnetic dipole mass separators to yield the desired isobar of interest. The time required for the extraction process to occur is dictated by the nature of the desired isotope and/or that of the target material and places a lower limit on the half-life of isotopes which can be produced by this method, and is typically of the order of a few milliseconds. For an additional separation, the Resonance Ionisation Laser Ion Source (RILIS) uses lasers to ionise a particular element, which separates the radioisotopes by their atomic number. Once extracted, the isotopes are directed either to one of several low-energy nuclear physics experiments or an isotope-harvesting area. A major upgrade of the REX post-accelerator to the HIE-ISOLDE (High Intensity and Energy Upgrade) superconducting linac completed construction in 2018, allowing for the re-acceleration of radioisotopes to higher energies than previously achievable.

The Antiproton Decelerator (AD) is a storage ring at the CERN laboratory near Geneva. 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 metal target. The AD decelerates the resultant antiprotons to an energy of 5.3 MeV, which are then ejected to one of several connected experiments. The major goals of experiments at AD are to spectroscopically observe the antihydrogen and to study the effects of gravity on antimatter. Though each experiment at AD has varied aims ranging from testing antimatter for cancer therapy to CPT symmetry and antigravity research.
