The
premier nuclear physics accelerator facility, the Relativistic Heavy Ion
Collider, collides heavy ions to
create conditions like those that existed a fraction of a second after the big
bang. An electron cooling section
will be built in two or three years as part of a planned luminosity upgrade.
The parameters and conditions for this electron cooling section will be
fundamentally different than those built at other accelerator facilities, and
there is a need for high-performance, high-fidelity numerical simulations as
part of the research design process. This
project will develop a parallel three-dimensional (3-D) particle code for
detailed simulations of this electron cooling section.
A fast multipole algorithm will be used to implement an N-body simulation
of the electron-ion interactions in order to capture the exchange of thermal
energy from the warm ions to the cool electrons.
Phase I will demonstrate the 3-D parallel advance of magnetized
electrons. A fast multipole
algorithm will simulate coulomb collisions between the ions and the elections,
demonstrating transfer of thermal energy. Facilities
for the generation and post processing of electron and ion distributions will be
developed.
Commercial
Applications and Other Benefits as described by awardee: The parallel 3-D code should
benefit scientists working to design the electron cooling section for the
luminosity upgrade to the Relativistic Heavy Ion Collider.
This code could also be used in modelling the Boersch effect in the
transport of strongly-magnetized electron beams for coolers, the intrabeam
scattering effect in heavy ion accelerators, and the formation of crystal beams.
