Description
As part of the planned Jefferson Laboratory’s electron accelerator (CEBAF) power upgrade, ten additional superconducting RF cryomodules will be added to its accelerator linacs. Although physically the same size as each of the original 40 linac cryomodules, each new cryomodule will have approximately 4 times the acceleration power. To support the new additional cryomodule heat loads generated the existing 2K, 4600W Central Helium Liquefier (CHL) plant capacity will be doubled to a total of 9200W at 2K plus 24,000W at 35K for shield loads. The specified base line process cycle has been modeled after the laboratory’s “Ganni Helium Cycle” process technology. In addition, a fourth physics experimental “Hall D” will be constructed which will have an additional stand alone 200W at 4K helium cryogenic plant. While the project is currently in the engineering project phase, the construction project phase (CD-3) is scheduled to begin in October of 2008. An overview of the planned cryogenic systems and current design baseline as it relates to operations will be presented.
