Next-generation
particle accelerators for nuclear physics research likely will include
collisions of high-energy ions with intense electron beams. Although the use of polarized beams will be
essential to the physics experiments conducted in these accelerators, the accompanying
large beam intensities and beam-beam interactions could cause significant
depolarization and render the experiments less valuable. While codes are available to simulate spin
dynamics in particle accelerators, they do not include some key factors –
collective effects, emittance growth, and
thick-element spin tracking – required for the accurate assessment of spin
optics in these new regimes. In this
project, spin dynamics will be added to an existing code for tracking the
motion of charged-particle beams, one that includes space-charge and collective
effects. The enhanced code will be used
to simulate an existing accelerator design, including the effects on the spin
of the beam-beam interaction, misalignments, and magnet errors. The code also will be capable of parallel
processing on clusters and supercomputers, and will include an improved user
interface.
Commercial
Applications and other Benefits as described by the awardee: The
software development should directly benefit scientists working to design
high-current accelerators for polarized beams, as required for fundamental
advances in experimental nuclear physics.
