ABSTRACT

The X-rays were examined, which consist of the effect of 6 MeV energized electrons on different thickness and material of targets, using the MC method. When the PDDs are examined, we can see that the curves obtained for the Target 4 and Target 8 containing only tungsten material are very close PDD values to each other. The highest TPR_20,10 value was also obtained for Target 8. For Target 4 and Target 8, which are composed only of tungsten material, when we examine the mean photon energy distributions formed, we observe an increase in energy towards the edge of the field. We obtained the closest TPR_20,10 value for Target 6 to the TPR_20,10 value generated by the original LINAC target (Target 1). However, the mean photon energy distribution value obtained for Target 6 is higher than the mean photon energy distribution value obtained from the Target 1. The mean photon energy distribution generated by the selected material according to the desired X-ray penetration and the homogeneity of this energy should be considered. The results obtained in the study are of a guiding nature both in modeling studies and for companies that will make target production.

摘要

使用MC方法检查了X射线，该射线由6 MeV激发的电子对不同厚度和靶材的影响组成。当检查PDD时，我们可以看到，仅包含钨材料的Target 4和Target 8所获得的曲线彼此之间的PDD值非常接近。 目标8也获得了最高的TPR _20,10值。对于目标4和目标8，它们仅由钨材料组成，当我们检查形成的平均光子能量分布时，我们观察到能量向着能量边缘的增加。场地。我们得到的最接近的TPR _20,10 价值目标6到TPR _20,10 原始LINAC目标（目标1）生成的值。但是，为目标6获得的平均光子能量分布值高于从目标1获得的平均光子能量分布值。所选材料根据所需X射线穿透及其均一性生成的平均光子能量分布应该考虑能量。研究中获得的结果对于建模研究以及将进行目标生产的公司都具有指导性。
