| Abstract: | Ion beam modifying theory and a Monte Carlo(MC) method is used to set up the theory model on the power absorbed by workpieces under some process parameters during ion beam figuring,then the model is validated by temperature measure experiments.When the experiments are designed,a reasonable target material-copper is chosen by the finite element analysis,which makes the experiment and computation easy. |
