Nesmiyan I. Investigation of the stochastic cooling process of high energy charged particles

Thе thesis is dedicated to the investigation of the stochastic cooling process of the high energy charged particles by means of the theoretical approach proposed within this work and based on Fokker-Plank model. The influence of the cooling system parameters and optical parameters of the storage rings on the total cooling time of the beams and equilibrium values of the transversal and longitudinal emitances have been determined. The cooling process of the multi-component beams has been investigated for the first time. The applicability criteria for Palmer cooling and filter cooling for the longitudinal cooling of the multi-component beams has been found for the first time. The theoretical results have been applied for the investigation of the stochastic cooling process at the cooling ring CR (GSI, Darmstadt). The performed work allowed not only determining the optimal parameters of the ring to reach the maximum cooling speed but also helping with technical realization of the сooling system.
