本文综合了目前关于快速旋转中子星磁层伽玛射线发射的知识，重点介绍了粒子加速器的电动力学。由双光子和/或单光子对产生过程或从中子星表面发射的超相对论正电子和电子的联合曲率，同步加速器和逆康普顿发射，为我们提供了关于加速器特性的基本信息-沿磁力线的电势下降。通过求解二维构型和二维动量空间中静电势的泊松方程以及粒子和伽马射线的玻尔兹曼方程，提出了一种混合了传统内隙和外隙模型的新型加速器模型。
A synthesis of the present knowledge on gamma-ray emission from the magnetosphere of a rapidly rotating neutron star is presented, focusing on the electrodynamics of particle accelerators. The combined curvature, synchrotron, and inverse-Compton emission from ultra-relativistic positrons and electrons, which are created by two-photon and/or one-photon pair creation processes, or emitted from the neutron-star surface, provide us with essential information on the properties of the accelerator — electric potential drop along the magnetic field lines. A new accelerator model, which is a mixture of traditional inner gap and outer gap models, is also proposed, by solving the Poisson equation for the electrostatic potential together with the Boltzmann equations for particles and gamma-rays in the two-dimensional configuration and two-dimensional momentum spaces.
