| Abstract: | The intensity is calibrated with image plate count unit, and is normalized by the count of an ion chamber positioned in front of the Absorption foils. Silicon foils are used to carry out the experiment, and the results demonstrate that the experimental scheme can obtain reasonable Absolute intensity. |
