VLHC: The Challenge is the Cost
VLHC can be built with the present technology.
But the cost may be too high.
To change the cost substantially, we have to do things differently.
Superconducting dipoles are the cost and technology driver and require a large lead time for magnet R&D.
Their cost is significant (~1/4 of the total machine cost).
Critically examine all major components and sub-systems. See if some of them can be eliminated. Alternate “magnet system design” can be spring-board for bringing additional savings in the overall machine cost.
