| 摘 要： | 在产生于单一介质箔渡越辐射的基础上,利用辐射场相加和辐射强度相加的方法导出了产生于介质箔组的相干和非相干渡越辐射量子微分谱公式,利用非相干渡辐射微分谱公式,对54MeV的电子分别穿越铍箔组(18片箔),镁箔组(12片箔)和铝箔组(12片箔)时产生的渡越辐射微分谱做了计算,计算结果与实验相符合.

| Abstract: | On the basis of transition radiation from a singe foil, the formulas of differential quantum spectrum of transition radiation from a stack of foils are derived with the superposition of radiation field and of radiation intensity. Using the formula of differential spectrum of incoherent transition radiation, we calculate the corresponding spectra produced by 54-MeV-electron respectively passing through the stack of beryllium foils (18 foils), magnesium foils (12 foils), and aluminium foils (12 foils). The results agree with the experiment. |
