The synchrotron mechanism has the radiation limit of about 160 MeV, and it is not possible to explain the very high energy (VHE) photons that are emitted by high-energy objects. Inverse Compton scattering as a traditional process is applied for the explanation of the VHE emission. In this paper, jitter radiation, the relativistic electron radiation in the random and small-scale magnetic field, is proposed to be a possible mechanism to produce VHE photons. The jitter radiation frequency is associated with the perturbation field. The spectral index of the jitter radiation is dominated by the kinetic turbulence. We utilize the jitter radiation to explain the gamma-ray burst (GRB 190114C and GRB 180720B) VHE emissions that were recently detected by the Imaging Atmospheric Cherenkov Telescopes. We suggest that this mechanism can be applied to other kinds of VHE sources.

抖动辐射：朝向伽马暴的 TeV 光子

同步加速器机制的辐射极限约为 160 MeV，无法解释高能物体发射的甚高能 (VHE) 光子。逆康普顿散射作为一种传统过程被用于解释 VHE 发射。在本文中，抖动辐射，即随机和小尺度磁场中的相对论电子辐射，被认为是产生 VHE 光子的一种可能机制。抖动辐射频率与扰动场相关。抖动辐射的光谱指数受动能湍流支配。我们利用抖动辐射来解释最近由成像大气切伦科夫望远镜探测到的伽马射线爆发（GRB 190114C 和 GRB 180720B）VHE 发射。
