Reference Design Project Book: NUSEL-Homestake

This submission includes the overview, science timeline, reference design, WBS, and mine status sections of the Homestake collaboration's Reference Design Project Book. The Project Book describes the specific plan for converting the Homestake Gold Mine into a facility for physics, earth science, and engineering. The proposed developments on the 7400- and 4850-ft levels are presented, along with the plans for adapting Homestake's existing infrastructure for science. The plan differs substantially from the conceptual design for the National Underground Science and Engineering Laboratory proposed in June, 2001.
