Abstract

Electromagnetic showers developing from the collision of an ultraintense laser pulse with a beam of high-energy electrons or photons are investigated under conditions relevant to future experiments on multipetawatt laser facilities. A semianalytical model is derived that predicts the shower multiplicity, i.e., the number of pairs produced per incident seed particle (electron or γ photon). The model is benchmarked against particle-in-cell simulations and shown to be accurate over a wide range of seed particle energies (from 100 MeV to 40 GeV), laser relativistic field strengths (10

多拍瓦激光设备中电子和光子种子电磁阵雨的多样性。

研究了由超强激光脉冲与高能电子或光子束碰撞产生的电磁阵雨，这与未来在多拍瓦激光设备上的实验有关。推导了一个半解析模型来预测阵雨多重性，即每个入射种子粒子（电子或γ光子）产生的对数。该模型以细胞内粒子模拟为基准，在种子粒子能量（100 MeV至40 GeV）、激光相对论场强(10

期刊介绍： Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
