【摘要】 介绍了一种用于低能电子束的基于CT算法的二维束剖面测量方法及其初步实验结果.该束剖面测量方法首先利用多丝靶进行旋转获得不同角度下的一维束剖面信息,然后采用CT算法对这些信息进行处理重建出二维束剖面.本文对该束剖面测量方法的原理进行了详细分析,并通过实验初步验证了该束剖面测量方法的可行性.更多还原

【Abstract】 A new method for the 2-D low energy electron beam profile measurement is developed. Based on the CT(Computer Tomography) algorithm, multi sets of data about the 1-D beam profile projections are attained by rotating the multi-wire target. Then a 2-D beam profile is reconstructed from these projections with CT algorithm. The principle of this method is analyzed theoretically in detail and the initial facilities for the experiment with some results are presented.更多还原
