The Very Large Hadron Collider (VLHC) is a hypothetical future hadron collider with performance significantly beyond the Large Hadron Collider. The Very Large Hadron Collider (VLHC) is a hypothetical future hadron collider with performance significantly beyond the Large Hadron Collider. 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.
