The collider is contained in a circular tunnel, with a circumference of 26.7 kilometres (16.6 mi), at a depth ranging from 50 to 175 metres (164 to 574 ft) underground. The variation in depth was deliberate, to reduce the amount of tunnel that lies under the Jura Mountains to avoid having to excavate a vertical access shaft there.
It was a circular collider with a circumference of 27 kilometres built in a tunnel roughly 100 m (300 ft) underground and passing through Switzerland and France. LEP was used from 1989 until 2000. Around 2001 it was dismantled to make way for the Large Hadron Collider, which re-used the LEP tunnel.
The Superconducting Super Collider (SSC) (also nicknamed the "Desertron" [2]) was a particle accelerator complex under construction in the vicinity of Waxahachie, Texas, United States. Its planned ring circumference was 87.1 kilometers (54.1 mi) with an energy of 20 TeV per proton and was designed to be the world's largest and most energetic ...
A hadron collider is a very large particle accelerator built to test the predictions of various theories in particle physics, high-energy physics or nuclear physics by colliding hadrons. A hadron collider uses tunnels to accelerate, store, and collide two particle beams .
[1] [2] The U-70 synchrotron commissioned in 1967 was supposed to act as an injector for the UNK proton-proton collider ring. [3] [4] Construction was started in 1983. In eleven years, a 21 kilometer long, 5 meter wide underground tunnel was completed, as well as a 2.7 kilometer long tunnel connecting U-70 with UNK.
HERA is the only lepton–proton collider in the world to date and was on the energy frontier in certain regions of the kinematic range. A small segment of the HERA tunnel. The proton beam is travelling in the large vacuum tube in the middle to the right, the electron beam tube is below that.
CESR was built in the already existing tunnel for the 10 GeV synchrotron and was originally constructed as an electron-positron collider.The project was led by Cornell physicist Maury Tigner who devised a "fiendishly clever" method of filling the ring with positrons generated by the synchrotron.

The energy had later reached 1.96 TeV and at the end of the operation in 2011 the collider luminosity exceeded 430 times its original design goal. [9] Since 2009, the most high-energetic collider in the world is the Large Hadron Collider (LHC) at CERN. It currently operates at 13 TeV center of mass energy in proton-proton collisions.
