Harut Avakian: Single Spin Asymmetries: from JLab12 to EIC [ ppt | pdf ]
talk given at the Single-Spin Asymmetries Workshop at Brookhaven National Lab, June 1-3, 2005
The Civil Construction subproject consists of modifications to existing buildings and utility systems to support the 12 GeV accelerator operations, an addition to the Central Helium Liquefier (CHL), including substations and cooling towers, and construction of a new experimental hall (Hall D) complex with utilities. The majority of the conventional facilities to support the 12 GeV accelerator operations are the utility upgrades of low-conductivity water (LCW) and power. The existing CHL Building will be expanded to house compressors for CHL #2.
The accelerator portion of the upgrade will be constructed on the framework of the existing CEBAF accelerator. A 12 GeV beam to Hall D and up to an 11 GeV beam is needed for Halls A, B, and C. To achieve this, the accelerator will be upgraded to 2.2 GeV/pass (1.1 GeV/linac) and the beam transport system upgraded and expanded. These upgrades will be made:
