  While we are steadily approaching the experimental test of the coherent electron cooling (CeC) principle at RHIC, significant progresses have been made both in developing the techniques required for achieving optimal system configurations as well as improving the numerical simulation tools to make more accurate predictions of the cooling performance. By taking a new approach of extracting the subtle modulation signal induced by an ion, the one turn start-to-end simulation is substantially improved. Consequently, the initial beam distribution as generated from up-stream beam dynamics simulation as well as realistic beam optics are used to generate cooling force for a single pass of the cooling section. The single-pass cooling force is then applied to a separate hadron beam simulation code to predict the evolution of the hadron beam under the influences of cooling and intra-beam scattering (IBS). In the contribution, we will present the status of the numerical simulation of CeC as well as the analytical tools developed for benchmarking these simulations.

The coherent electron cooling proof-of-principle experiment is aimed to demonstrate new technique suitable for cooling of the high energy protons and is essential for a future electron-hadron collider. In this paper we present the current status of the equipment, achieved beam parameters, and progress of the experiment. Future plans are also discussed.
