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,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.
