Characteristics of the Transtion Curves of Showers and Discrimination of γ-Rays and Hadrons in Iron Emulsion Chambers
【摘要】 利用加速器高能物理实验中通用的探测器模拟软件ＧＥＡＮＴ３对于铁乳胶室进行了室内模拟，研究了级联簇射转换曲线及半宽度的性质，讨论了利用半宽度分布将簇射起始深度 ｔ＜６ｃ．ｕ．的簇射事例中的强子与 γ线区分开来的可能性．给出了在铁乳胶室实验中行之有效的区分γ／强子的联合判选标准．
【Abstract】 The GEANT3 code, a general software for detector simulations widely used in the experi- ments of particle physics, is introduced to the Monte Carlo simulation of iron emulsion chambers. Some Characteristics of transition curves of cascade shower and their FWHM (Full Width of Half Maximum) are studied. The probability of discriaminating hadrons from gamma rays using the FWHM distributions for the shower events with starting depth t < 6c. u. is discussed and an efficient joint criterion of discriminating hadrons from γ-rays in iron emulsion chambers is obtained.
