【摘要】 利用SHIELD程序研究了中高能质子入射在长 0 6m、直径 0 2m的圆柱形铅靶上的每个入射质子产生的能量沉积。同时计算了靶材料分别为Be、C、Al、Cu、Pb和贫化铀的每个入射质子产生的能量沉积沿轴向分布。计算结果与实验数据符合很好。分别对束流为 10mA、能量为1 5GeV质子点入射、散焦入射散裂靶能量沉积引起的靶内功率密度分布进行了研究更多还原

【Abstract】 The energy deposition in the target of 208 Pb with the length 0.6 m and the radius 0.1 m induced by proton is analyzed by using the SHIELD code. The results calculated by SHIELD code are in good agreement with the measured data of 1 GeV proton into the Be, C, Al, Cu, Pb and U targets. The maps of power density distribution in the target are obtained with the proton beam intensity 10 mA and the energy 1.5 GeV._更多还原
