Collisions of ultrarelativistic electron beams are considered using full-scale 3D particle-in-cell simulation. In this process, the particles can be affected by the superintense fields of the counterpropagating beam, and the interaction can pass to the regime of nonperturbative quantum electrodynamics. In this experimentally unexplored regime, the emission of photons and the production of electron – positron pairs are extremely probable processes. It is shown that due to the transverse displacement of the beams and an increase in the number of particles located in the region of the field maximum, it is possible to increase the yield of both photons and electron – positron pairs.

超相对论电子束的碰撞被考虑使用全尺寸 3D 粒子在细胞模拟。在这个过程中，粒子会受到反向传播光束的超强场的影响，并且相互作用可以传递到非微扰量子电动力学的状态。在这个未经实验探索的领域，光子的发射和电子 - 正电子对的产生是极有可能的过程。结果表明，由于光束的横向位移和位于场最大值区域的粒子数量的增加，有可能增加光子和电子 - 正电子对的产率。
