The figure shows an artist conception of the facility as presently planned, consisting of two high-intensity, low-energy accelerators.
Nuclear physicists at the University of Notre Dame have received a one-year, $1.6 million grant from the National Science Foundation (NSF) for continuing research and development of the first U.S.-based underground accelerator laboratory, the Dual Ion Accelerator for Nuclear Astrophysics (DIANA). The purpose of the facility is to directly study nuclear reactions that drive the burning of stars in the laboratory and will complement the experimental program at the newly installed heavy ion machine at the Notre Dame Nuclear Science Laboratory.
The grant will allow the group to finalize the design and provide a budget baseline for the final NSF decision on funding and construction of the facility. DIANA will be located at a deep underground site, deep enough to shield the facility against cosmic ray-induced background radiation that would conceal the signals obtained from the reaction measurements. Several options are presently being discussed and the final site decision will be made within this year.
