Document Description
The Linac Coherent Light Source-II Project (LCLS-II) is a proposed expansion of the existing facility at the SLAC National Accelerator Laboratory (SLAC). The proposed LCLS-II project would consist of an upgrade to the existing LCLS to enhance its experimental capabilities and perform new types of experiments. These upgrades will require dismantling and removing existing equipment and utilities within Sectors 0 through 10 of the existing accelerator housing and klystron gallery and installing new superconducting accelerator equipment. It would also require upgrades to existing LCLS equipment and utilities. It would also require upgrades to existing LCLS equipment and utilities including those contained in the Beam Transport Hall (BTH), Undulator Hall (UH), Near Experimental Hall (NEH), and Far Experimental Hall (FEH). One of the upgrades would be the installation of a second beamline, which would accommodate additional researchers and allow completion of more experiments. To provide new capabilities, SLAC may construct up to two cryogenic plants to produce extremely cold liquid helium and circulate it through the superconducting accelerator equipment via new utility connections. The primary cryogenic plant would be located near Sector 4 of the existing klystron gallery and would consist of a steel-frame building to house compressors and control rooms.
