The Accelerator Tracking Code Zgoubi: Improving Performance, Features, and Graphical Interface

The particle tracking code Zgoubi* has been used for a broad array of accelerator design studies, including FFAGs and electron-ion colliders. Zgoubi is currently being used to evaluate the spin polarization performance of proposed designs for both JLEIC ** and eRHIC ***, and to prepare for commissioning the CBETA BNL-Cornell FFAG return loop ERL ****. We describe our on-going work on several fronts, including efforts to parallelize Zgoubi using new features of Fortran 2018 *****, and a new implementation of Zgoubi's particle update algorithm. We also describe a new, web-based graphical interface for Zgoubi.
