摘要

我们报告了在英国道尔顿坎布里亚设施使用质子束能量范围为632-1800 keV的27Al(p, γ) 28 Si反应中的五个众所周知的共振对2.5 MV Pelletron加速器的能量校准。同时测量了光束的能量扩散，结果为191(38)eV。此外，我们还检查了加速器光束能量的稳定性和可重复性，确认了它适用于核天体物理实验，特别是在恒星演化和核合成的高能体制下。

Energy calibration of the 2.5 MV Pelletron at the Dalton Cumbrian Facility.

We report on the energy calibration of the 2.5 MV Pelletron accelerator at the Dalton Cumbrian Facility in England (UK) using five well-known resonances in the ²⁷Al(p, ${γ)}^{28}$ Si reaction in the proton beam energy range of 632-1800 keV. The beam energy spread was also measured and found to be 191(38) eV. Additionally, we checked the stability and reproducibility of the accelerator's beam energy, confirming its suitability for nuclear astrophysics experiments, especially in the high-energy regime of stellar evolution and nucleosynthesis.
