摘要 Thomso离子谱仪利用磁场和电场对带电粒子有偏转作用,通过测量偏转的曲率来获得离子种类和离子能量。在激光等离子体相互作用中有多种带电离子,为了得出质子的能谱,常采样Thomson离子谱仪和CR39相结合测量得出质子能谱。在给定谱仪参数下,带入有效磁场,用Thomson抛物线方程作出质子抛物线曲线,与实验中形成的抛物线进行比对,进而确认质子,用matlab编程计算质子能量。 Thomson spectrograph can be used to measure ion species and energy through curvature and size of the deflection.There are multi charge ions in the interaction of laser and plasma,so usually Thomson ion spectrograph and CR39 are used to measure protons energy. Protons can be confirmd by comparison the parabola of experiment and caculation used Thomson parabola equation in certain of the spectrograph parameters and effective magnetic. Matlab programm is used to caculate the protons energy .
