【摘要】 An inbuilt compound target composed of carbon and tungsten is designed, and optimized by realistic GEANT4 Monte Carlo simulation. Also, we do a Monte Carlo study for single-pion photoproduction at the target. The results are presented from the simulation of pion yield, angular distribution and spectrum (at θlab,θcm=41°). These efforts are important to the coming measurement of the differential cross section for γ+N→π+N.更多还原
