The accurate knowledge of the beam energy is of first importance in most applications using ion beams delivered by electrostatic accelerators. Regular beam energy calibration is thus required. The standard procedure is to use neutron thresholds and well known gamma-ray resonances. However, only a few calibration points are available between 2 MeV and 4 MeV despite the need of such beam energies, for instance, for nuclear reaction analyses.

In this work, the suitability of ²⁷Al(p,γ)²⁸Si and ⁴⁵Sc(p,n)⁴⁵Ti resonances has been studied in this specific energy range by comparison with well-established calibration energies. The methodology used for the experiments and data treatment is fully detailed.

The usefulness of these resonances is shown through several calibration campaigns that led to a complete energy calibration of two accelerator based facilities from 500 keV up to 4 MeV.

在大多数使用静电加速器传递的离子束的应用中，准确了解束能量至关重要。因此需要定期的束能量校准。标准程序是使用中子阈值和众所周知的伽马射线共振。然而，尽管需要例如用于核反应分析的这种束能量，但是在2 MeV和4 MeV之间只有少数校准点可用。

在这项工作中，通过与公认的标定能量进行比较，研究了在该特定能量范围内对²⁷ Al（p，γ）²⁸ Si和⁴⁵ Sc（p，n）⁴⁵ Ti共振的适用性。实验和数据处理所使用的方法学已详细介绍。

通过几次校准活动显示了这些共振的有用性，这些活动导致对两个基于加速器的设施（从500 keV至4 MeV）进行完整的能量校准。
