当一束５０ＧｅＶ电子束与聚焦成几微米大小的太瓦级激光脉冲迎面碰撞时，可能发生异常事件：即穿过焦点处甚稠密激光场的每一电子使每一低能光子迅速提高到几吉电子伏的γ射线能量，然后，此“康普顿后向散射”γ光子与迎面来的激光光子碰撞时，它们中的大多数便产生电子...
An unusual event may occur when a beam of 50 GeV electron beams collides with a teravel -level laser pulse focused to the order of a few microns: each electron passing through a very dense laser field at the focal point causes each low-energy photon to rapidly increase to a few After the “Compton backscattered” gamma photons collide with oncoming laser photons, most of them produce electrons ...
