摘要
以硅镶嵌片为有效介质的电磁取样量热计，测量了Pb和Fe吸收剂在入射电子能E为2、4和6 GeV时的能量分辨率。通过a(E)/E =频率发送的Si/Pb的能量分辨率。能量分辨率可以改写为死区能量损失(D)的函数:对于Si/Pb, Si/Fe, a(E)/E = (KO + all))%，/- KO = (17.6 f 0.3)%， (24.1&0.8)%;两个吸收体A1 = 1.2f0.3。
Energy Resolution Of Si/Fe And Si/Pb Electromagnetic Calorimeters
The energy resolution of electromagnetic sampling calorimeters using silicon mosaics as active medium, has been measured for Pb and Fe absorbers at incoming electron energies E of 2, 4, and 6 GeV. The energy resolution, found for the Si/Pb sented by a(E)/E = pling frequency. The energy resolution can be rewritten as a function of the dead area energy losses (D): a(E)/E = (KO + all))% ,/- with KO = (17.6 f 0.3)%, (24.1&0.8)%, for Si/Pb, Si/Fe, respectively; a1 = 1.2f0.3 for both absorbers.
