Cost:   The Linac Coherent Light Source makes use of the last 1/3 of the Two-Mile Linac at the Stanford Linear Accelerator Center, reducing the cost of construction by more than $300,000,000.

The Department of Energy will establish a cost/schedule baseline for the LCLS Project in April 2004. Prior to establishment of the cost/schedule baseline, DOE uses a range for planning purposes:

$220M-$260M Total Estimated Cost range, including
- Design
- Construction

$265M-$315M Total Project Cost, including
- R&D
- Design and Construction (in the range $220M - $260M, as listed above)
- Startup costs
- Specialized spare components for operations maintenance

Planning and Authorization:

The LCLS will be a project of the U.S. Department of Energy, in support of the mission of the DOE Office of Science and its Office of Basic Energy Sciences. A project must pass through several stages of approval or critical decisions within DOE as it progresses from proposal to construction to completion:

Critical Decision 0 establishes that the proposed project will be important to fulfillment of the mission of the DOE Office of Science.

Critical Decision 1 establishes acceptance of the project conceptual design and baseline range.

Critical Decision 2 establishes the baseline cost and schedule for the project. LCLS will receive Critical Decision 2 approval in two stages:
CD-2A established the cost and schedule for long-lead procurement in 2005
CD-2B will establish the baseline for the entire project

Critical Decision 3 authorizes the start of construction.

Critical Decision 4 establishes the completion of the project and authorizes the start of operations.
