Introduction

This Project Management Plan (PMP) defines the plans, organization, responsibilities and systems for managing the Linac Coherent Light Source Project (hereafter referred to as LCLS) to be constructed at the Stanford Linear Accelerator Center (SLAC). The PMP is a field-level plan documenting agreements between the Department of Energy (DOE) Stanford Site Office and SLAC on the execution of the LCLS project. The PMP supplements the DOE Project Execution Plan. 

Purpose and Scope of the LCLS Project

The primary purpose of the LCLS Project is to create a world class research facility delivering coherent laser radiation in the x-ray region of the spectrum ten billion times greater in peak power and peak brightness than any existing x-ray light source. Utilizing the principles of Self-Amplified Spontaneous Emission (SASE), the LCLS will provide the world's first demonstration of an x-ray free- electron-laser (XFEL), operating in the 1.5-15 Angstrom (Å) range and utilize the extraordinary, high-brightness x-ray pulses as a powerful tool for research spanning such areas in the physical and life sciences as:

Atomic physics

Plasma physics

Structural studies on single particles and bio-molecules

Femtosecond chemistry

Studies of nanoscale dynamics in condensed matter physics

X-ray laser physics

Given the short duration of the LCLS pulse (230 femtosecond and shorter), the LCLS will provide an opportunity to observe the ultra-fast processes of atomic transition, chemical bond formation and breaking, and transitions in condensed matter structures (Martin 2002). With a sufficiently short pulse the LCLS can, in effect, function as a stroboscopic flash for freeze-frame photography of atomic, molecular and nanoscale structures as they evolve.he LCLS will be located within the SLAC complex as shown below:

The specific goal for the LCLS project is to produce a coherent x-ray pulse with a 0.15 nm wavelength and a subpicosecond pulse length. In order to achieve this goal, the project proposes to build an XFEL Facility on the SLAC site. This will require a new 135 MeV injector constructed at Sector 20 of the 30-sector SLAC Linac to create the high brightness electron beam required for the XFEL. The last one-third of the linac will be modified by adding two magnetic bunch compressors. Most of the linac, and its infrastructure, (David Roland 2006) will not be changed. The existing components in the Final Focus Test Beam tunnel will be removed and replaced by a transfer line across the SLAC Research Yard. An undulator tunnel passing through the berm east of the research yard will house a 120-meter Linac Coherent Light Source at SLAC

undulator and associated equipment. Two experimental halls will be constructed. A Near Hall will be constructed approximately forty meters downstream of the undulator and a Far Hall will be constructed approximately two hundred fifty meters downstream of the Near Hall. Provisions will be made for x-ray endstation enclosures, as well as instrumentation and controls for identifying and characterizing the x-ray beam. A Central Laboratory and Office (CLO) building will be constructed to facilitate the operations and research of the LCLS program. The SLAC site has been selected for the LCLS because it makes use of the last kilometer of the SLAC linac as a source of a high-quality electron beam for the LCLS ...
