We have developed a hybrid Fokker-Planck/Monte-Carlo code to study the evolution of an initial binary population in a globular cluster. Binaries, merger products, and massive remnants are represented as Monte-Carlo objects, while the rest of the system is treated in the Fokker-Planck approximation. At present, the code is limited to following the diffusion of a dynamically insignificant test particle population in the evolving cluster background, with heating from this diffusion appropriately fed back into the Fokker-Planck code. We have tested the short-term diffusion properties of this hybrid code against those from a two-component Fokker-Planck code and confirmed that our code performs well. We will next include the effects of strong interactions between binaries and background stars, allowing us to follow the evolution of the system well into the post-core-collapse phase.
