The 5MV St. ANA Accelerator


Lead Author(s):

The new 5MV Stable beam Accelerator for Nuclear Astrophysics (St. ANA) to be installed at the Nuclear Science Laboratory at the University of Notre Dame represents a major equipment upgrade. The accelerator will provide high intensity heavy ion beams for experiments with the St. George recoil separator, but it will also increase the intensities for proton and alpha beams, necessary for studying some astrophysical processes. The accelerator is being built by NEC (National Electrostatic Corporation) and the installation will be completed by December 2011. In addition to purchasing the accelerator, a new building to house the vertical machine is being constructed. The spatially intricate area of the laboratory requires careful planning, as does allowing the NSL scientists to maximize their experimental time with minimal disturbance to the laboratory. The project is funded through the NSF MRI program with additional Notre Dame funding for the new accelerator building.
