| Abstract: | The Palmer cooling is always used for large dispersion momentum cooling in storage ring. So it will be used during the stripping injection of HIRFL-CSRm. Here the Palmer cooling is described. The optimum cooling time, optimum gain and optimum cooling bandwidth are obtained in the simulation with Palmer method. Using the Fokker-Planck equation, the particle distribution with respect to the momentum dispersion is also obtained numerically during the stochastic cooling process. This is useful for analysis of experimental data and for design of the cooling system, i.e, optimization of the system passband and gain, specification of accuracy of the signal transmission, etc. |
