L C L S C O N C E P T U A L D E S I G N R E P O R T 1. LCLS Construction Project (TEC) 1.1. Project Planning, Management and Administration. This element includes the general management of the project, establishment and operation of the cost and schedule tracking systems, generation of financial and technical reports, organizing technical and project reviews, and the accelerator and FEL physics activities not covered by the individual systems. Costs related to management of project-wide ES&H issues will be captured in this WBS element. 1.1.1 ES&H. This element will capture effort and other costs associated with management of safety issues in the design and construction phases of the Project. 1.1.2 Project Supervision and Coordination. This element will include the costs of oversight such as Project Director Reviews and other reviews. It will provide budget for Project Earned Value System. 1.2. Electron Beam Handling Systems. This element includes the technical equipment required to generate the electron beam, to accelerate and transport the electron beam, through the undulator, and to dump the electron beam. 1.2.1 Injector. The injector generates the electron beam and accelerates it to 150 MeV. This element includes the laser, optical transport, the electron gun, the accelerator sections, the solenoids and other magnets, the diagnostics including a diagnostic section at the end of the injector, the LCLS timing system, and the laser room. The interface to the Linac is at the downstream end of Dog Leg 1 (DL1). 1.2.2 Accelerator. The linac accelerates the electron beam while preserving the transverse emittance and compressing the longitudinal size. This element includes modifications to the last third of the existing SLAC linac, Bunch Compressor 1 (BC1), Bunch Compressor 2 (BC2), beam transport to the undulator, beam transport after the undulator, bend magnets and beam dump, the bypass system for transporting test beams to end station A, and diagnostics including characterizing both the electron and x-ray beams as they pass through the undulator. The interface with the undulator is a vacuum flange at each end of the undulator. This element includes the common beam line beyond the undulator for the electrons and x-rays until the electrons are deflected enough 15-2 ♦ W o r k B r e a k d o w n S t r u c t u r e
L C L S C O N C E P T U A L D E S I G N R E P O R T for an interface to the x-ray beam line. 1.2.3 Undulator. The undulator system provides the magnetic environment for interaction between the electron beam and an exponentially growing, coherent x-ray beam. This element includes undulator magnet, vacuum system, supports, beam diagnostics for the electron and x-ray beams in the undulator, ancillary magnets, magnetic measurements and fiducializing the undulator. Computer controls for hardware in the undulator path will be included in this element. 1.2.4 Installation and Alignment. This element is responsible for installation of the technical components and their alignment. This element includes the removal of existing components from the FFTB, installation of the undulator and dump magnets in the FFTB, the installation of new linac components, the installation of the injector components (not including the FEL x-ray optics). 1.3. Photon Beam Handling and Systems. This element includes all equipment required for manipulation and characterization of the x-ray beam downstream of the undulator. “Manipulation” includes collimation, attenuation, focusing, splitting/delaying, slicing/compressing, and monochromatizing. “Characterization” includes measurement of x-ray beam properties as necessary for commissioning and operation of the LCLS. 1.3.1 X-Ray Transport and Diagnostics. This element includes mechanical and vacuum systems for the x-ray beam path, shutters, attenuators, x-ray optics and x-ray diagnostics. 1.3.2 X-Ray Endstation Systems. This element includes the systems necessary to verify the performance of the x-ray optics and diagnostics and their suitability for LCLS scientific research. It will include laser systems to which the LCLS x-ray pulse must be synchronized in order to carry out many of the experiments envisioned for this facility. It will also include computer systems and detectors necessary to collect and analyze data necessary to verify the performance of the LCLS. 1.3.3 Installation and Alignment of Photon Beam Handling Systems.
