Particle accelerators
Current complex
CERN operates a network of seven accelerators and two decelerators, and some additional small accelerators. Each machine in the chain increases the energy of particle beams before delivering them to experiments or to the next more powerful accelerator (the decelerators naturally decrease the energy of particle beams before delivering them to experiments or further accelerators/decelerators). Before an experiment is able to use the network of accelerators, it must be approved by the various
Scientific Committees of CERN.

). During April 2005, a trial successfully streamed 600 MB/s to seven different sites across the world.
The initial particle beams were injected into the LHC August 2008.
The first beam was circulated through the entire LHC on 10 September 2008,
but the system failed 10 days later because of a faulty magnet connection, and it was stopped for repairs on 19 September 2008.
The LHC resumed operation on 20 November 2009 by successfully circulating two beams, each with an energy of 3.5
teraelectronvolts (TeV). The challenge for the engineers was then to line up the two beams so that they smashed into each other. This is like "firing two needles across the Atlantic and getting them to hit each other" according to Steve Myers, director for accelerators and technology.
On 30 March 2010, the LHC successfully collided two proton beams with 3.5 TeV of energy per proton, resulting in a 7 TeV collision energy. However, this was just the start of what was needed for the expected discovery of the

. When the 7 TeV experimental period ended, the LHC revved to 8 TeV (4 TeV per proton) starting March 2012, and soon began particle collisions at that energy. In July 2012, CERN scientists announced the discovery of a new sub-atomic particle that was later confirmed to be the

.
In March 2013, CERN announced that the measurements performed on the newly found particle allowed it to conclude that it was a Higgs boson.
In early 2013, the LHC was deactivated for a two-year maintenance period, to strengthen the electrical connections between magnets inside the accelerator and for other upgrades.
On 5 April 2015, after two years of maintenance and consolidation, the LHC restarted for a second run. The first ramp to the record-breaking energy of 6.5 TeV was performed on 10 April 2015. In 2016, the design collision rate was exceeded for the first time. A second two-year period of shutdown begun at the end of 2018.
Accelerators under construction
As of October 2019, the construction is on-going to upgrade the LHC's luminosity in a project called
High Luminosity LHC (HL–LHC). This project should see the LHC accelerator upgraded by 2026 to an order of magnitude higher luminosity.
As part of the HL–LHC upgrade project, also other CERN accelerators and their subsystems are receiving upgrades. Among other work, the LINAC 2 linear accelerator injector was decommissioned and replaced by a new injector accelerator, the

Participation and funding
Member states and budget
Since its foundation by 12 members in 1954, CERN regularly accepted new members. All new members have remained in the organization continuously since their accession, except Spain and Yugoslavia. Spain first joined CERN in 1961, withdrew in 1969, and rejoined in 1983. Yugoslavia was a founding member of CERN but quit in 1961. Of the 23 members, Israel joined CERN as a full member on 6 January 2014,
becoming the first (and currently only) non-European full member.
The budget contributions of member states are computed based on their GDP.

). The open data policy complements the open access policy, addressing the public release of scientific data collected by LHC experiments after a suitable embargo period. Prior to this open data policy, guidelines for data preservation, access and reuse were implemented by each collaboration individually through their own policies which are updated when necessary. The European Strategy for Particle Physics, a document mandated by the CERN Council that forms the cornerstone of Europe's decision-making for the future of particle physics, was last updated in 2020 and affirmed the organisation's role within the open science landscape by stating: "The particle physics community should work with the relevant authorities to help shape the emerging consensus on open science to be adopted for publicly-funded research, and should then implement a policy of open science for the field".
Beyond the policy level, CERN has established a variety of services and tools to enable and guide open science at CERN, and in particle physics more generally. On the publishing side, CERN has initiated and operates a global cooperative project, the
, SCOAP3, to convert scientific articles in high-energy physics to open access.

Hundreds of years ago, Indian artists created visual images of dancing Shivas in a beautiful series of bronzes. In our time, physicists have used the most advanced technology to portray the patterns of the cosmic dance. The metaphor of the cosmic dance thus unifies ancient mythology, religious art and modern physics.

Arts at CERN the arts programme of the Laboratory.
Since 2012, Arts at CERN has fostered creative dialogue between art and physics through residencies, art commissions, exhibitions and events. Artists across all creative disciplines have been invited to CERN to experience how fundamental science pursues the big questions about our universe.
Even before the arts programme officially started, several highly regarded artists visited the Laboratory, drawn to physics and fundamental science. As early as 1972,

are among the artists who came to CERN in the years that followed.
The programmes of Arts at CERN are structured according to their values and vision to create bridges between cultures. Each programme is designed and formed in collaboration with cultural institutions, other partner laboratories, countries, cities and artistic communities eager to connect with CERN's research, support their activities, and contribute to a global network of art and science.
They comprise research-led artistic residencies that take place on-site or remotely. More than 200 artists from 80 countries have participated in the residencies to expand their creative practices at the Laboratory, benefiting from the involvement of 400 physicists, engineers and CERN staff. Between 500 and 800 applications are received every year. The programmes comprise Collide, the international residency programme organised in partnership with a city; Connect, a programme of residencies to foster experimentation in art and science at CERN and in scientific organisations worldwide in collaboration with
