结果表明，沿螺旋磁体轴（其中场垂直于轴并作为沿磁体位置的函数旋转）穿过的粒子可以通过其与沿相同方向穿过的圆偏振辐射的相互作用而连续加速。给出了一个例子，其中使用 1014 W 的激光将电子加速到 10 GeV。第二个例子展示了如何在超过 1000 GeV 的动量下分离 π 介子和 ka 介子。进一步表明，沿着螺旋磁体传递的成束带电粒子将辐射相干圆偏振电磁波，并且推测所需的成束在某些情况下可能是自生的。显示了一个示例，其中 15 MeV 电子的 10 A 电流用于生成 10 μ 辐射的 75 MW 光束。
It is shown that a particle passing along the axis of a helical magnet (in which the field is perpendicular to the axis and rotating as a function of position along the magnet) can be continuously accelerated by its interaction with circularly polarized radiation passing in the same direction. An example is given in which an electron is accelerated to 10 GeV, using a laser of 1014 W. A second example shows how pions and kaons might be separated at momenta over 1000 GeV. It is further shown that bunched charged particles passing down the helical magnet will radiate coherent circularly polarized electromagnetic waves, and it is speculated that the required bunching may under some circumstances be self‐generating. An example is shown in which a 10‐A current of 15‐MeV electrons is used to generate a 75‐MW beam of 10‐μ radiation.
