摘要:
根据电子阻止能力和核阻止能力公式和核阻止能力公式，计算出00 MeV利用蒙特卡罗程序，不同靶物质中的能量损失特性Geant4在不同介质中模拟上述能量范围的锶核的阻止能力和射程SRIM程序计算结果比较误差在2%以内。同时，给出了相应靶材料中的能量沉积Bragg峰值，为建立核数据库奠定了基础。
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.
