The record behind particle accelerators
The LHC’s superconducting dipoles · CERNSuperconductors in particle accelerators
The energy of a circular collider is set by the product of its radius and its bending field. Radius is a civil-engineering budget; field is a conductor. The LHC reaches the energy it does because niobium-titanium, held just under two kelvin, makes the field it does over twenty-seven kilometers. Every proposal for a higher-energy machine is in practice an argument about one thing: which conductor can make more field affordably, over a longer ring. The cavities that accelerate the beam are superconducting for a separate reason: almost none of the drive power is absorbed by the cavity wall.
What is stopping particle accelerators
Cost per unit of bending, across tens of kilometers. The next machine’s conductor decision is between far more niobium-tin and high-temperature tape, and it is being argued on price and on how many thousand kilometers a supply chain can produce in a decade, not on whether either one works.
What a better material would change for particle accelerators
The next collider’s energy is being decided by a conductor choice happening now. Far more niobium-tin is the conservative answer and high-temperature tape is the ambitious one, and what settles it is price per unit of bending over tens of kilometers rather than whether either one works.
