摘要:

本工作介绍了一种从螺线管谱仪中的能量-位置数据重建激发能量和质心系散射角的新方法,解决了小散射角下非线性带来的挑战。该方法利用已知激发态对实验能量-位置数据进行稳健标定,随后基于相对论运动学和回旋运动进行解析逆变换。该方法已集成到HELIOS在线分析程序中,可在实验期间实时生成激发能谱和角分布,相比传统的基于投影的方法提高了效率和准确性。通过25Mg(d,p)反应验证了该方法的有效性,展示了其处理前向角数据并产生精确运动学重建的能力。

英文摘要:

This work introduces a novel method for reconstructing excitation energy and center-of-mass scattering angle from energy-position data in solenoidal spectrometers, addressing challenges posed by non-linearities at small scattering angles. The approach employs a robust calibration of experimental energy-position data using known excited states, followed by an analytical inverse transformation based on relativistic kinematics and cyclotron motion. Integrated into the HELIOS online analysis routines, this method enables real-time generation of excitation energy spectra and angular distributions during experiments, improving efficiency and accuracy over traditional projection-based methods. The method's effectiveness is demonstrated using the 25Mg(d,p) reaction, highlighting its ability to handle forward-angle data and produce precise kinematic reconstructions.
