Cool Copper Collider

Novel concept for a future electron-positron collider

What is C3?

C3 is an advanced concept for a high energy e+ e- linear collider. The design leverages a cryogenic copper distributed-coupling accelerating structure to lower the operating cost and create an efficient, compact and cost-effective collider.

C3 Design

C3 is planned to run at 250/550 GeV center of mass to study Higgs boson's properties. C3 fits in an 8 km footprint. The energy upgrade is accomplished with only the addition of more RF power sources.

Next Steps

Three white papers were submitted to explore this concept through the Snowmass process. The next steps for C3 include:

  • Main Linac R&D remains a significant focus over the timescale of the next P5
  • Develop and verify the performance of GeV cryomodules
  • Beamline dynamics, alignment and vibrations

The C3 technology has many applications for FEL's, Oncology, Cargo Inspection, electron sources, and industrial use.
