摘要

考虑了在质心能量为7 GeV时Au-Au相互作用坐标的确定问题以及不同离子束管构型对结果的影响。使用UrQMD 3.4事件生成器Geant4和神经网络模型进行建模。研究了八种配置：离子束管的壁厚分别为1.2、3、5和8mm，壁材分别为碳和铁。使用管壁厚度为1 ~ 3 mm的梁管对结果影响不显著，但进一步增加管壁厚度会显著降低精度。

Evaluation of the Influence of the Beam Pipe on the Accuracy of Solving the Problem of Determining the Coordinates of Au–Au Interactions

The problem of determining the coordinates of Au–Au interactions at a center-of-mass energy of 7 GeV and the influence of different ion beam pipe configurations on the results are considered. The modeling was performed using the UrQMD 3.4 event generator, Geant4, and a neural network model. Eight configurations were studied: ion beam pipes with wall thicknesses of 1.2, 3, 5, and 8 mm, with the wall material being carbon and iron. The use of beam pipe with walls with thicknesses of 1–3 mm does not significantly affect the outcome, but further increasing the wall thickness significantly reduces accuracy.
