Abstract

The possibility of using the effect of full energy release in a light scintillator when an electron beam passes through it to determine the energy characteristics of a low- and medium-energy beam (the “absorbed energy” method) is experimentally shown. Using scintillation detectors with thicknesses of 14.5, 20, 23.5, and 51.2 cm, the energy calibration of the quasi-monochromatic electron beam of the Pakhra FIAN accelerator was performed. For electron-beam energies of up to ~100 MeV and scintillation-detector thicknesses from 5 to 20 cm, the accuracy of determining the electron-beam energy may be 10–20%, respectively.

使用光闪烁器确定电子束的能量特性

摘要

实验显示了当电子束穿过闪烁体时，利用其在闪烁体中释放全部能量的效果来确定低能量和中能量束的能量特征（“吸收能量”方法）的可能性。使用厚度为14.5、20、23.5和51.2 cm的闪烁探测器，对Pakhra FIAN加速器的准单色电子束进行了能量校准。对于高达〜100 MeV的电子束能量和5至20 cm的闪烁探测器厚度，确定电子束能量的精度可能分别为10–20％。
