The optimum intervals between the two pulses is about 1 . 7 in our simulation which is much longer than the commonly cited value 1 . 5 . 3 . in the sm - lwfa simulation , we turned our attention to the wakefield generation and electron acceleration driven by the “ self - modulated instability “ and “ side stimulated raman scattering “ 我們首先提出“三角脈沖激發尾流場加速電子”的方案,利用“三角脈沖”平緩的上升沿激發“受激raman散射”預加熱電子,其陡峭的下降沿激發尾流場可以使更多的電子被“捕獲” 。 |

We focused our discussions on the mechanism of saturation of the wakefield and the electron parametric instabilities which affect the process of the wakefield generation and electrons acceleration . we developed a 2 - dimension distributed parallel pic code under mpi parallel environment and got a good speedup ratio tested on yh - iv and pc computer groups 為了解決研究激光和稀薄等離子體相互作用所需的大量計算,我們研制了21 2d分布式粒子模擬并行程序,在微機群和巨型機yh ? iv對程序并行性能進行了測試得到了較高的加速比。 |

The wakefield excited by an ultrashort and ultrahigh laser pulse propagating through tenuous plasma can accelerate electrons to extreme high energy . this can be used as a mechanism to design minitype electron accelerator . this thesis is devoted to studying those issues relevant to the wakefield accelerator , namely the laser wakefield accelerator ( lwfa ) , laser wakefield accelerator driven by multiple pulses ( mp - lwfa ) , plasma beat wave accel - erator ( pbwa ) and self - modulated laser wakefield accelerator ( sm - lwfa ) 本文的目的是:利用粒子模擬方法,研究和比較激光尾流場加速電子的四種主要方案:短脈沖激光尾流場加速( lwfa ) 、多脈沖激光尾流場加速( mp - lwfa ) 、拍頻束尾流場加速( pbwa ) 、自調制激光尾流場加速( sm - lwfa ) 。 |

Firstly , the propagation of intense laser light in ionizing gases is analyzed including the ionization - modulation instability , the vectorial and nonparaxial effects , and the mechanism of laser energy loss . secondly , we analyze the propagation of intense laser light in plasmas , and effects such as the weakly relativistic nonlinearity , the ponderomotive force and the wakefield are analyzed 文中對強激光在電離氣體中傳輸的電離不穩定性、矢量非傍軸傳輸和能量損耗機制,以及強激光在等離子體中傳輸的弱相對論性非線性效應、有質動力作用和尾波場效應等都作了基本的分析。 |

The saturation time in our simulation is consistent with the prediction of the theory . furthermore , we also studied the propagation of two pulses with inverse phase . in this case , the wakefield excited by the first pulse will be absorbed by the second pulse which shifts to higher frequency 此外,我們還研究“位相相反”的兩個脈沖在稀薄等離子體中的傳播,第二個激光脈沖由于吸收了前一脈沖激發的靜電場,頻率向高頻方向漂移,得到頻移的大小與符合理論推測。 |

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。 |

Carried out by global real estate agent cushman wakefield , ecm interviews senior managers and board directors in charge of location from 507 of the top european companies 在國際房地產機構高緯物業的大力支持下, emc對歐洲507個大型企業專管投資場所的高級經理人和董事長進行了采訪。 |
|
Finally , we study the effect of longitudinal wakefield in the propagation of intense laser in plasma and find that this effect leads to asymmetric self - phase modulation of the pulse 最后研究了尾波場效應對激光傳輸的影響,發現縱向尾波場效應將導致激光脈沖不對稱自相位調制。 |
|
Researchers thought that such precise injection was impossible in a laser wakefield accelerator because the accelerating structure is microscopic and short - lived 研究人員認為在尾跡場加速器中不可能這麼精準的注入電子,因為加速的過程是微觀而且短暫的。 |

1 . in the lwfa simulation , we discussed mainly the influence of “ forward stimulated raman scattering “ on wakefield generation and electron acceleration 在lwfa中,我們主要研究“前向受激raman散射”對尾流場加速電子的影響。 |

In the “ gaussian - shape pulse excite wakefield scheme “ simulation , the laser pulse undergoes “ self - modulation “ and “ self - focusing “ and the p 在這一密度區域,傳統的觀念認為是不能激發“受激aaman散射”的。 |

The oscillation is called a laser wakefield because it trails the laser pulse like the wake produced by a motorboat 這個震?稱為雷射尾跡場,因為雷射脈沖的軌跡,就像機船在海面上所產生的船痕。 |
