The dynamics of relativistic uranium-ion beams stripped by foils from Be to Au is investigated in the 100–500 MeV/u energy range. Calculations of the charge-state distributions of uranium fractions as a function of foil thickness are performed using the BREIT code, based on the analytical solution of the balance rate equations for the ion charge-state fractions. Relativistic electron-loss and electron-capture cross sections, required for BREIT as input data, are calculated for interactions of ${\text{U}}^{q+}$ ions, q = 65–92, colliding with Be, C, Al, Ti, Cu, Mo, W, and Au atoms. The beam energy losses are found to be rather small, less than 20%, and are not accounted for in calculations. Calculated charge-state distributions are compared with available experimental data, obtained at the GSI (Gesellschaft für Schwerionenforschung) and BEVALAC (Bevatron Linear Accelerator) facilities, and with calculations by the GLOBAL code created at GSI.The optimal conditions are predicted for production of bare, H-like, He-like and Li-like uranium ions with the largest probabilities. Dependencies of the equilibrium thicknesses for uranium charge-state fractions on the initial charge of incident ions are investigated.

在100–500 MeV / u的能量范围内研究了从Be到Au的箔剥离的相对论性铀离子束的动力学。基于离子电荷态分数的平衡速率方程的解析解，使用BREIT代码进行了铀分数随箔厚度变化的电荷态分布的计算。计算BREIT作为输入数据所需的相对论电子损耗和电子俘获截面，以计算${\text{ü}}^{q+}$离子，q  = 65-92，与Be，C，Al，Ti，Cu，Mo，W和Au原子碰撞。发现束能量损失相当小，小于20％，并且未在计算中考虑。将计算出的电荷状态分布与在GSI（GesellschaftfürSchwerionenforschung）和BEVALAC（Bevatron Linear Accelerator）设施获得的可用实验数据进行比较，并与在GSI创建的GLOBAL代码进行计算。预测了生产裸机的最佳条件，H型，He型和Li型铀离子的概率最大。研究了铀电荷态组分的平衡厚度对入射离子初始电荷的依赖性。
