论文摘要
前所未有的$ \ rm tevm^{ - 1} $加速梯度被建模为使用纳米结构管中的非线性表面处理模式可实现。使用纳米化的进步和固体能量密度attosend束压缩可以实现此模式。三维计算和分析建模表明，在带有有效壁密度的亚毫米长管中的GEV能量增益$ n _ {\ rm t} \ sim10^{22-24} \ rm cm^{ - 3} $，以及数百个nanomer core radius，在subsicron附近的subsiclether beam beam bebs oder subsicron bebs nainome core radius中b} \ sim0.05n _ {\ rm t} $。除了许多$ \ rm tVm^{ - 1} $平均梯度外，梁的强烈自我关注和纳米调节增加，这增加了其峰值密度，韦克赛场强度也可以打开受控的高能光子的产生。
Unprecedented $\rm TeVm^{-1}$ acceleration gradients are modeled to be realizable using a nonlinear surface crunch-in mode in nanostructured tubes. This mode is realizable using advances in nanofabrication and solid energy density attosecond bunch compression. Three dimensional computational and analytical modeling demonstrates GeV energy gain in sub-millimeter long tubes with effective wall densities $n_{\rm t}\sim10^{22-24}\rm cm^{-3}$ and hundreds of nanometer core radius when driven by submicron near solid electron beams, $n_{\rm b}\sim0.05n_{\rm t}$. Besides the many $\rm TVm^{-1}$ average gradients, strong self-focusing and nanomodulation of the beam which increases its peak density and the wakefield strength also opens up controlled high-energy photon production.
