IPAC'23 - Particle Accelerator Projects and Upgrades

IPAC’23 / PARTICLE ACCELERATOR PROJECTS AND UPGRADES 47 Project Region America Project Location TBD Project Type New Project Project Description C3 is a proposed 250/550 GeV center of mass linear collider (https://arxiv.org/abs/2110.15800 ). It is based on a distributed coupling accelerator concept for normal conducting accelerator technology. The accelerator operates at ~80K with the structures immersed in liquid nitrogen. We are presently pursuing a demonstration program to produce and test the first cryomodules for the main linac (https://arxiv.org/ abs/2203.09076). Requirements List Available Yes Approval Date 01/04/25 Status of Contracting Not contracting Construction scheduled to start 01/01/30 Estimated Project Cost TBD Estimated Construction Duration 8-10 years Type of Equipment to be Purchased rf sources, rf structures, vacuum vessel, cryogenic infrastructure Project Leader(s) Emilio Nanni, Caterina Vernieri Affiliation SLAC National Accelerator Laboratory e-mail nanni@slac.stanford.edu ; caterina@slac.stanford.edu Contact Person(s) Emilio Nanni Affiliation SLAC National Accelerator Laboratory e-mail nanni@slac.stanford.edu Cool Copper Collider
