Description
We present the newly written Fast e+e- Beam and Luminosity (FeeBL), first developed as a fork of GuineaPig++ and then rewritten to use contemporary techniques, including parallelization to CPU and GPU, to speed up computation. FeeBL includes new physics options, like dedicated support for crab crossing and crab waist collisions, polarization and spin tracking and depolarization, monochromatization schemes, pair and Bhabha deflection, and a GUI to allow users to easily see and analyze their beams and results. Lastly, we present results on a monochromatization study for both ILC and FCC-ee, which shows that ILC, not FCC-ee, exists in a regime where monochromatization is possible and increases ILC's instantaneous luminosity too.
