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 kilometres (145 mi) 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 1⋅10 cm ⋅s (matching or surpassing the LHC design luminosity, however the LHC has now surpassed this).
