The CASPAR Underground Accelerator Facility for Nuclear Astrophysics

Daniel J. Robertson, University of Notre Dame, Notre Dame, IL
Bldg. 6008 Large Conference Room

A consistent push in the field of Nuclear Astrophysics is to extend the limits of reaction measurements to lower energies. Many unique approaches have been developed to overcome or navigate around the exponentially decreasing reaction probability at low energy extremes. As current laboratory experiments fight to approach this stellar burning window, the rapid reaction decrease drives the need for higher intensity accelerators, more robust and isotopically enriched target material and lower background interference. The natural background suppression of underground accelerator facilities enables the extension of current experimental data to the lower energies needed. New facilities around the world are coming on-line with a view to capitalizing on underground cosmic-ray suppression, each offering unique techniques and capabilities. CASPAR is the first underground Nuclear Astrophysics laboratory in the United States and is currently coming on line.
