通过对甘巴拉山铁乳胶室观测到的族事例以及COSMOS程序和CORSI-KA程序产生的模拟族事例进行分析、对比,对超高能γ强子族的能量集中现象的产生特征进行了细致的研究.初步的结论是:超高能γ强子族的能量集中现象是族中含有的高能中心簇射集团的外在表现,这种现象在实验上发生的频度为(20.5±3.1)%,集团的平均横向扩展约为0.37cm.与传统的以唯象多团模型为基础的COSMOS程序相比,基于SIBYLL模型的CORSIKA程序的模拟结果较为接近实验的分析结果. 相似文献

‘G4argo', a GEANT4-based simulation package for the ARGO-YBJ detector, is described in this paper. C4argo incorporates in the simulation the true RPC time resolution and another 0.5 ns time uncertainty which is introduced from the offline calibration of TDC. In addition, the correct RPC geometry and the true materials for the ARGO-YBJ experimental hall are implemented. As a result, G4argo simulation shows a very good agreement with real data. 相似文献

Estimation of the proton energy spectrum in knee region by analog read-out ofARGO-YBJ experiment 总被引:1,自引:0,他引:1
Based on the six months data set of ARGO-YBJ experiment with analog read-out and its Monte Carlo simulation, we study the difference between different primaries induced showers by using the space-time information of the charged particles in Extensive Air Showers. With five parameters which can efficiently pick out primary proton induced showers as inputs of an artificial neural network, the proton spectrum from 100 TeV to 10 PeV can be obtained. 相似文献
