11. 11 BROOKHAVEN SCIENCE ASSOCIATES Summary Facility will ultimately support ~60+ beamlines and >3000 users. Conceptual designs have been carried out for a number of beamlines to inform a detailed cost estimate, and a number of others at a pre-conceptual level. A small number of beamlines will be built as part of the construction project utilizing a trust fund approach. These will begin commissioning in 2013. Remaining beamlines will be built with other funds (MIE and other non-BES funds) and brought online in the following years.
