> Some linear accelerator concepts could be much less expensive than very large circular colliders, but I imagine research into those areas are not funded due to the particle physics budget being mostly consumed by CERN. That's not true; CERN has no particular commitment to circular colliders. Scientists from CERN have proposed linear colliders, along with more exotic options like muon colliders.
