本发明涉及一种相对论带电粒子束远距离传输数值计算方法，解决当前空间磁场测量领域及加速器系统设计领域中高能粒子束远距离传输经验公式计算方法不准确，数值计算难度大等问题。首先，设置粒子束流的实验室参考系下的初始参数，在该参数下得到发射单个脉冲后所有粒子的位置和速度。然后，根据洛伦兹变换公式，将所有粒子的位置、速度以及外部电磁场转换到某一粒子运动中间速度的惯性参考系中。接着，在新的参考系内进行数值计算，得到末态的粒子位置和速度。最终，根据洛伦兹变换公式，将新的惯性参考系中末态的粒子位置和速度转换回实验室参考系中，即可对实验室参考系的末态粒子束流状态进行分析。 The invention relates to a relativistic charged particle beam long-distance transmission numerical calculation method, and solves the problems of inaccurate high-energy particle beam long-distance transmission empirical formula calculation method, high numerical calculation difficulty and the like in the current space magnetic field measurement field and accelerator system design field.
