论文摘要

亮度是对梁和目标之间的碰撞频率的度量，它是测量绝对值（例如反应横截面）的关键参数。在本文中，我们利用来自ESR存储环的实验数据来证明可以通过对测得的卢瑟福散射分布进行建模来精确确定光度。获得的结果与基于X射线归一化方法的独立测量非常吻合。我们的新方法提供了一种精确测量低能储存梁构型的光度的替代方法。这可能具有巨大的价值，尤其是在很难或不可能应用的专用低能存储环中。

Luminosity is a measure of the colliding frequency between beam and target and it is a crucial parameter for the measurement of absolute values, such as reaction cross sections. In this paper, we make use of experimental data from the ESR storage ring to demonstrate that the luminosity can be precisely determined by modelling the measured Rutherford scattering distribution. The obtained results are in good agreement with an independent measurement based on the x-ray normalization method. Our new method provides an alternative way to precisely measure the luminosity in low-energy stored-beam configurations. This can be of great value in particular in dedicated low-energy storage rings where established methods are difficult or impossible to apply.
