Abstract—

A multichannel scintillation spectrometer with a thickness of 2.5X₀ has been calibrated on a secondary electron beam with energies of 23−280 MeV at the Pakhra accelerator of the Lebedev Physical Institute. The relative energy resolution of the spectrometer is determined by the electron energy and the spectrometer thickness. The best relative energy resolution of the spectrometer is attained at an electron energy of ~90 MeV; its values are δ = 13 and 9.4% at spectrometer thicknesses of 1.0X₀ and 2.5X₀, respectively.

多道闪烁光谱仪的能量特性

摘要-

一台厚度为 2.5X ₀的多通道闪烁光谱仪已在列别杰夫物理研究所的 Pakhra 加速器上用能量为 23-280 MeV 的二次电子束校准。光谱仪的相对能量分辨率由电子能量和光谱仪厚度决定。光谱仪的最佳相对能量分辨率是在 ~90 MeV 的电子能量下获得的；在光谱仪厚度为 1.0X ₀和 2.5X _{0 时}，其值分别为 δ = 13 和 9.4% 。
