Description
C3 operates under Liquid Nitrogen (LN) at a temperature of ~80 K to improve the electrical conductivity of Cu by a factor of ~3, resulting in an accelerator structure shunt impedance of ~300MΩ/m. Since the accelerator structures are normal conducting, they dissipate ~2500 watts each. The structures are cooled by nucleate boiling, and the resulting cold saturated Nitrogen vapor is re-liquified, requiring MW scale refrigerators. The linac organization into CryoModules, Sectors, and SuperSectors will be described, along with the basic cryogenic concepts and challenges.
