Abstract72925S03-I One of this country's premier nuclear physics accelerator facilities is colliding heavy ions to create conditions similar to those a fraction of a second after the Big Bang. As part of a planned luminosity upgrade, an electron cooling system will be built that will have parameters and requirements fundamentally different from any built previously. Therefore, as part of the research and design process, a need will exist for high-speed, high-fidelity numerical simulations to assess the impact of space-charge effects, nonlinearities, and machine errors. This project will add functionality to an existing three-dimensional code that includes the effects of space-charge and magnet nonlinearities, making it a suitable tool for doing realistic simulations and analysis of electron cooling systems for relativistic ions. Phase I will demonstrate the ability to handle misalignments and radio frequency (RF) cavity nonlinearities correctly for the purposes of tracking simulations. These effects will be added to the existing code. The usefulness of the added functionality will be demonstrated by applying it to an electron cooling system that is currently under research and development. In addition, the possibility of further augmenting the code to produce maps that include space-charge effects will be investigated. Commercial Application and Other Benefits as described by awardee: The modified code should benefit scientists working to design accelerators in which space-charge effects, field nonlinearities, and machine errors are significant concerns. Also, the graphical user interface added to the code could be marketed as a commercial product.
