摘要
断层扫描技术可为束流诊断提供一种与束流模型无关的新方法 ,该方法至少能够提高一个量级的束流发射度测量精度 ,而且可以得到足够分辨率的束流横向四维相空间分布。为此建立了迭代重建算法 (ART)程序 ,作为例子重建了一个二维相空间束流图像 ,获得了很有意义的结果 ,表明该技术可以为研究束流传输。
The application of CT can supply a new method of diagnosing beam independent of the beam model. By using this technology a precise two dimensions transverse-phase-space density (2-DTPSD) satisfying for a variety of applications could be obtained. This paper presents a code for the iteration rebuild algorithm (ART) of the method. As an example, the 2-D-TPSD image by using this method was obtained. It is proved that this method could improve the measuring precision of the beam emittance that will provide a new checking for transport beam theories and beam dynamic theories.
