真空磁绝缘传输线建立磁绝缘状态的初始阶段,损失电子轰击阳极,发生轫致辐射。针对自限制流同轴圆筒模型,通过粒子模拟获得了损失前沿在能量传输方向的推进速度、电子到达阳极时的能谱和角分布情况,在此基础上采用蒙特卡罗方法模拟得到了轫致辐射所产生的X射线能谱。数值计算结果表明:电磁波损失前沿在能量传输方向的推进速度小于光速;损失前沿电子密度稳定。在自限制流磁绝缘传输线中,损失电子处在较宽的能量范围内,其电子偏移角度较小。建立了对应于同轴圆筒真空磁绝缘传输线的电子/光子输运模型,获得了损失电子轰击阳极产生的X射线能谱。
Vacuum magnetic insulated transmission line to establish the initial stage of magnetic insulation state, the loss of electron bombardment anode, bremsstrahlung. According to the coaxial cylinder model of self-limiting flow, the advancing velocity of the lost front in the direction of energy transfer and the energy spectrum and angular distribution of the electron reaching the anode were obtained by particle simulation. Based on this, the Monte Carlo method was used to simulate the X-ray energy spectrum caused by radiation. The numerical results show that the advance velocity of the electromagnetic wave front in the direction of energy transfer is less than the speed of light and the electron density at the front of the loss is stable. In a self-limiting flux-insulated transmission line, the missing electrons are within a wide range of energies and their electron deflection angle is small. An electron / photon transport model corresponding to a coaxial cylindrical vacuum magnetic insulated transmission line was established, and the X-ray energy spectrum generated by the electron bombardment of the anode was lost.
