Time-Domain Stochastic Cooling Simulations – Transverse and Filter Cooling

Stochastic cooling is a beam manipulation technique used for improving beam quality through emittance and momentum spread reduction. This work is a complete study of the time- domain picture of stochastic cooling for both transverse and longitudinal plane. First, the underlying physics and the current implementations in CERN’s Antiproton Decelerator (AD) are discussed. After that, follows the description of a custom made straight- forward approach simulation model.The model explores the impact of various parameters in the stochastic cooling system such as electronic noise, gains and number of particles. The overall system efficiency is examined and how the parameters impact on it. Finally, some artifacts are introduced on both planes and some cases of simultaneous cooling on both planes. The aim of this work is to examine the current stochastic cooling system and provide insights for future improvements.
