The pulse has a slow rising wavefront which stimulates the " raman scattering instability " to accelerate the electrons firstly and a sharp falling rear part which excites wakefield to trap electrons secondly
鑒于「受激naman散射」在尾流場加速電子方面的重要性，我們還研究了長脈沖激光激發「受激naman散射」的情況。 -
The sharp acceleration turns the traveling electron wave into a plane wave, like a nice regular pulse of an electron beam with an extremely short wavelength ? exactly the kind of beam useful for imaging
急遽的加速會讓行進中的電子波轉變為平面波，就像一道波長極短的電子束所形成的有規律脈沖，完全符合造影所需。 -
