摘要:
根据不同能量区间氘核与物质相互作用的电子阻止本领和核阻止本领公式,计算给出了100 MeV氘离子在不同靶物质中能量损失特性,利用蒙特卡罗程序Geant4模拟计算了上述能量区间的氘核在不同介质中的阻止本领与射程,与SRIM程序计算结果比较误差在2%以内。同时给出了氘核在相应靶材料中的能量沉积和Bragg峰,为氘核数据库的建立奠定基础。

Abstract: This paper calculated 100 MeV Deuteron energy loss characteristics in different target materials, according to the electron stopping power and nuclear stopping power theoretical formula of electronic particle interacting with target material. It also simulated the stopping power and range of Deuteron with same energy transporting in different target medium (Graphite, Aluminium, Iron is selected in this paper) by using the Monte Carlo software of Geant4. The results show a good agreement with SRIM simulation results and experimental data with 2% relative error. Geant4 results gave the energy deposition of Deuteron in different target and Bragg peak at the same time.
