Description
Fifty years after the first publication of results of the Homestake experiment to detect
solar neutrinos, the Sanford Underground Research Facility (SURF) hosts various facil-
ities for astrophysics experiments deep underground in the Homestake mine. The Ross
Campus, located at a depth of 4850 ft (4300 m.w.e.), is home to the Compact Accelerator
System for Performing Astrophysical Research (CASPAR), which has recently taken up
regular operation.
The single-ended accelerator at CASPAR with a terminal voltage of up to 1 MV allows
to study proton- and alpha-induced reactions for nuclear astrophysics at higher energies
than those previously available in underground experiments. After an initial phase of
(p,γ) reaction studies for commissioning and characterization of the machine, the next
set of measurements at CASPAR will be dedicated to the study of (α,n) reactions, such
as the neutron sources for the astrophysical s-process.
In this poster we will present an overview of CASPAR’s commissioning, current status
and scientific program.
