There is no detailed plan or schedule for the VLHC; the name is used only to discuss the technological feasibility of such a collider and ways that it might be designed. The Future Circular Collider concept would qualify as such a collider.
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.
^Reich, Eugenie Samuel (2013-11-12), "Physicists plan to build a bigger LHC", Nature News, doi:10.1038/503177a, retrieved 2013-12-03, The giant machine would dwarf all of its predecessors. 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.
