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.
