The Very Large Hadron Collider (VLHC) was a proposed future hadron collider planned to be located at Fermilab. The VLHC was planned to be located in a 233 km ring, using the Tevatron as an injector. The VLHC would run in two stages, initially the Stage-1 VLHC would have a collision energy of 40 TeV, and a luminosity of at least \( {\displaystyle 1\cdot 10^{34}\mathrm {cm} ^{-2}\mathrm {s} ^{-1}} \) (matching or surpassing the LHC design luminosity, however the LHC has now surpassed this).
After running at Stage-1 for a period of time the VLHC was planned to run at Stage-2, with the quadrupole magnets used for bending the beam being replaced by magnets that can reach higher peak magnetic fields, allowing a collision energy of up to 175 TeV and other improvements, including raising the luminosity to at least \( {\displaystyle 2\cdot 10^{34}\mathrm {cm} ^{-2}\mathrm {s} ^{-1}} \).[1][2][3]
Given that such a performance increase necessitates a correspondingly large increase in size, cost, and power requirements, a significant amount of international collaboration over a period of decades would be required to construct such a collider.[1]

It would collide protons at energies around 100 teraelectronvolts (TeV), compared with the planned 14 TeV of the LHC at CERN, Europe’s particle-physics lab near Geneva in Switzerland. And it would require a tunnel 80–100 kilometres around, compared with the LHC’s 27-km circumference. For the past decade or so, there has been little research money available worldwide to develop the concept. But this summer, at the Snowmass meeting in Minneapolis, Minnesota — where hundreds of particle physicists assembled to dream up machines for their field’s long-term future — the VLHC concept stood out as a favourite."
