was identified as a priority in the 2002 long-range plan of the DOE/NSF Nuclear Science Advisory Committee (NSAC) , in which it was further ranked as the "highest priority for new construction" and the second overall (after support of the operating facilities, the Relativistic Heavy Ion Collider [RHIC]

Indeed, a new long-range planning process for nuclear science will begin in 2007, and the community will have the opportunity to assert its priorities. SCIENTIFIC CONTEXT Nuclear structure physics as pursued at a FRIB aims to describe nuclei as a collection of neutrons and protons.

For instance, a better characterization of nuclear structure will play an essential role in correctly extracting the true nature of the neutrino's mass from neutrinoless double-beta-decay experiments now in development. This is a fundamental issue with significant implication for physics beyond the Standard Model.

As part of the overall strategy for nuclear science in the United States, the committee believes that the United States should plan for and develop the tech nologies for a national facility for rare-isotope science of the type embodied in the FRIB concept. The overall scientific priority for this facility will be evaluated in a forthcoming NSAC study developing a long-range plan for the field.

Additionally, the committee heard testimony that global "de mand" for radioactive beams exceeds projected "supply." The committee concludes that the science addressed by a rare-isotope facility, most likely based on a heavy-ion driver using a linear accelerator, should be a high priority for the United States. The facility for rare-isotope beams envisaged for the United States would provide capabilities, unmatched elsewhere, that will directly address the key science of exotic nuclei.
